It never showed the claimed button in the main toolbar even after relaunching and enabling/disabling the addon.

Version 1.7
Thunderbird 91.9.1
Linux Mint 20.3 cinamon

This review is for a previous version of the add-on (1.7).

TB team (as of March 30th, 2023):
The missing button is a customization issue and might be related to a bug which was fixed last year. The button can be manually returned in those case, by opening the customization.
