how to insert a ToolButton on Extras tab ?

[neal3000]

I'm trying to install a ToolButton on the extras tab ( after 📐button) , but cannot figure out how.

any suggestions appreciated.

I have it working for txt2img and img2img tab,
class Scripts(scripts.Script):
def after_component(self, component, **kwargs):

    # Add button to both txt2img and img2img tabs
    if kwargs.get("elem_id") == "txt2img_send_to_extras" or kwargs.get("elem_id") == "img2img_send_to_extras":
        tabname = kwargs.get("elem_id").replace("_send_to_extras", "")
        print(f"after_component {tabname}")
        upload_button = ToolButton('👺', elem_id=f'{tabname}_xx_button', tooltip="xxxx.")
        upload_button.click(fn=upload_button_click,
            inputs=[xxx], outputs=None)
