How to completely remove Thunderbird?

Installed Thunderbird on Ubuntu 24.04.1 LTS, tried to use it, got frustrated with it and now not wanting it on my system. Tried apt purge, remove, autoremove, autoclean. Nothing worked. It is still there and launching. There is no /.thunderbird in home dir. This is the first time I'm seeing such an un-removable software. How can I get rid of Thunderbird?
