Please add a Sieve icon to the Thunderbird Spaces Toolbar

Thunderbird version 102 has a Spaces Toolbar.

Can a Sieve icon please be added to the Thunderbird Spaces Toolbar?

Perhaps code pointers from the CardBook add-on can help as a CardBook icon shows in the Spaces Toolbar.

What do you think?

Thank you

I did experiments on this back in march, technically it should be only a few lines to implement this.

But reality bites, because the tab handling in the places toolbar api is badly broken.

For details refer to the following bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=1762058

If you look at the details of the ticket you see that the tab api and the places api are incompatible and fixing this needs a major change which is still pending.

And yes it is a bit saddening that Thunderbird was released and advertise a shiny new feature which has a badly broken API for addons.

Unless the API gets fixed there is not much which can be done here from an addon perspective.
