I propably took a wrong way to update Thunderbird.
I found in Ubuntu Software the TB icon for the new 91.4.0 version (December 29th 2021) and clicked the Install button.
When restarting email, it still opened the old 78.14.0 (from my Ubuntu 20.04.3 LTS). Clicking Applications icon I can find two identical Thunderbird icons. I understand there is somewhere a kind of starting points for two different versions of TB, but of course it is important to change the default. Should I manipulate those or do something differently from beginning?
I could not find a direct answer from How to update Thunderbird 78 to 91 on Ubuntu 20.04? or anyway I need more detailed instructions.
I am not very used to apt but noticed by apt show -a thunderbird
there are two TB packages but propably neither is the newest:

What is the basic difference between the installations of new and old versions? Are they both apt packages? How should I eliminate the old one?
