Assume you don't know the exact name of the application command. You can list the installed applications with apt command and use grep to search for the application name by guessing.

For example, you can do smart-guessing that the Google Chrome package should have chrome in its name. You may search it like this:

sudo apt list --installed | grep -i chrome

If you are not sure what the package does, you can always get its detail with:

sudo apt info google-chrome-stable

Once you know the exact package name, you can delete it using the apt autoremove command.

sudo apt autoremove google-chrome-stable
