I have installed in Ubuntu -> Outlook and Youtube using Progressive Web Apps: https://www.youtube.com/watch?v=3oCyfcHSeDc
However, I cannot find my new PWAs between my old apps, I restarted Ubuntu but unfortunately is not shown in "Show Applications"
In other distros PWA are added automatically: https://www.youtube.com/watch?v=u0wi7yecUdc
Probably I'm missing something, any help would be really appreciated!
Update: I'm using Ubuntu 20.04.1 LTS
