Return user of Linux distro------a lot of questions to follow I fear

I think I previously figured out how to add web site shortcuts to the desktop in Linux Mint but need help with Manjaro. What I have found so far is very technical and confusing.

Did you try webapp-manager?

What did you try exactly?

I came from mint about 12 months ago and I’m using manjaro-cinnamon edition. Apart from the package management (which I prefer on manjaro) most settings etc are the same as mint if that helps at all
