Unfortunately, the "Open Google Tasks" Add-on opens only another tab in Thunderbird, which only shows purely one selected list of tasks. Therefore, you do not get an overview of all your lists and tasks. So it is only a very limited view of some tasks.
The Add-on (v1.0) uses the following link to connect with Google tasks. If you try this, you can see what you will get:
https://assistant.google.com/tasks

It would be much better if the Add-on would use the following link instead. This link will provide the whole overview of all your lists and tasks. Which makes a lot more sense:
https://calendar.google.com/tasks

Another nice option would be, to be able to switch between both of these views.

Please T@ntely, it really would be great if you could change this.
(PS: Tested with Thunderbird v.115.18.0)

Quick, easy, and works perfectly. Excellent add on!
Note: You may have to change one setting in your google admin.google.com settings. Simply go into your admin page and search "search and assistant settings" and make sure you have "access to workspace data through assistant" set to "On".
