Trouble in removing ms teams application from Ubuntu 20.04

I used the command below to remove teams permanently:

sudo apt purge teams

However, when I check with sudo apt list | grep teams I see the app names below: (base) user@user-pc:~$ sudo apt list | grep teams WARNING: apt does not have a stable CLI interface. Use with caution in scripts. python3-openid-teams/focal,focal 1.2-2 all t1-teams/focal,focal 4.17 all teams-insiders/stable 1.5.00.10453 amd64 teams/stable 1.5.00.10453 amd64 When I attempt to remove those apps, it can't find them. Also, when I reinstall Teams, it remembers my user name from the previous login. This indicates that there are still some config or log files somewhere. How can I completely remove the Microsoft Teams app (with all config files and preferences) from my Ubuntu OS?
