Automatically open an gmail addon card without user clicking on the addon icon

I am looking for a way (I understand does not really seem a good idea) to force my gmail addon to automatically open a card and display the same.

Basically, the addon should check the current email’s tags and then autotrigger some ‘showPanel’ of the addon.

I see some answers about google sheets, but not getting how to go about this in the gmail addon without user triggering it.

Additional Chrome Extension way ??:
If this is not something possible. I also have a chrome extension (which the users will have installed) clicking on a link created by the chrome extension can I somehow trigger the addon icons click event ?

Apologies if this basic stuff, not able to find any direct useful info.
