How to customize EdgelessElementToolbarWidget or AffineImageToolbarWidget?

[khangho-vgames]

I have try to use this

  class PatchPageServiceWatcher extends BlockServiceWatcher {
    static override readonly flavour = 'affine:page';

    override mounted() {
      const pageRootService = this.blockService as PageRootService;
      const onFormatBarConnected = pageRootService.specSlots.widgetConnected.on(
        (view) => {
          if (view.component instanceof AffineFormatBarWidget) {
           view.component.clearConfig(). /* --- */ .addToggle();
          }
        }
      );
      pageRootService.disposables.add(onFormatBarConnected);
    }
  }

To change the text format bar and it works.

But now if I try to do the same for ElementToobar or ImageToolbar, there is no function exposed like the FormatToolbar.
Have try this for the ImageToolbar but didn't work:

  function configureImageToolBar(imageToolbar: AffineImageToolbarWidget) {
  // I copy this straight from the Source code.
  const Account = ({
      width = '1em',
      height = '1em',
      style = '',
    } = {}) => html`
      <svg
        xmlns="http://www.w3.org/2000/svg"
        viewBox="0 0 24 24"
        width=${width}
        height=${height}
        fill="none"
        style=${'user-select:none;flex-shrink:0;' + style}
      >
        <path
          fill="currentColor"
          fill-rule="evenodd"

    `;

    const newButton = {
      type: 'primary',
      items: [
        {
          type: 'download',
          label: 'Download',
          icon: Account,
          generate: ({ blockComponent }) => {
            return {
              action: () => {
                blockComponent.download();
              },
              render: (item) => html`
                <editor-icon-button
                  class="image-toolbar-button download"
                  .tooltip=${item.label}
                  .tooltipOffset=${4}
                  @click=${(e: MouseEvent) => {
                    e.stopPropagation();
                    item.action();
                  }}
                >
                  ${item.icon}
                </editor-icon-button>
              `,
            };
          },
        },
        {
          type: 'caption',
          label: 'Caption',
          icon: Account,
          when: ({ doc }) => !doc.readonly,
          generate: ({ blockComponent }) => {
            return {
              action: () => {
                blockComponent.captionEditor?.show();
              },
              render: (item) => html`
                <editor-icon-button
                  class="image-toolbar-button caption"
                  .tooltip=${item.label}
                  .tooltipOffset=${4}
                  @click=${(e: MouseEvent) => {
                    e.stopPropagation();
                    item.action();
                  }}
                >
                  ${item.icon}
                </editor-icon-button>
              `,
            };
          },
        },
      ],
    };

    imageToolbar.addPrimaryItems([newButton]); // shouldn't it work here?
  }

  class ImageBlockServiceWatcher extends BlockServiceWatcher {
    static override readonly flavour = 'affine:image';

    override mounted() {
      const imageBlockService = this.blockService as ImageBlockService;
      const onFormatBarConnected =
        imageBlockService.specSlots.widgetConnected.on((view) => {
          if (view.component instanceof AffineImageToolbarWidget) {
            configureImageToolBar(view.component);
          }
        });
      imageBlockService.disposables.add(onFormatBarConnected);
    }
  }

Anyone has any idea? Or it's currently impossible to extend these toolbars?

I want to customize almost all the toolbar to suit my project but seems like that is not an option yet...
