For exemple,in Ubuntu 14:04 you can add a link from the launcher to the desktop and then right-click and open properties an add "google-chrome --password-store=basic" in Command:
But this is not possibly in Ubuntu 20:04. I have tried to go to Settings --> Application --> Chromium, but there are no way to add something in Command: as above.

If this concerns a launcher that you placed on the desktop, then find the corresponding .desktop file in your Desktop folder, open it with a text editor and edit the Exec= line.
For a launcher that appears in the Application overview which you want to edit, copy the launcher .desktop file from the system folder /usr/share/applications (or possibly other places for applications installed as a snap package) to the folder .local/share/applications under your home folder. .local is a hidden folder. Turn "view hidden files" on in the file manager to see that folder in your home folder. Customize the launcher by editing the .desktop file.
