New user. Linux Mint how do I set up appimage?

I signed up because you guys work with Linux, but no tutorial is correct. I use Linux Mint and Opera browser and I’m trying hard to figure out how to get something to load the appimage and set up a virtual drive on my system.

I’m not an expert, I’m a weekend warrior with Linux.

First of all, if you didn’t do it yet, right click on the downloaded file and check it as executable. Then try to follow this:

It still won’t launch

It is in the app menu but when I try to launch it from gear lever or the app menu, it doesn’t load still

From your screenshot I see you have a final double quote on your last command, could it be a typo?

I wondered about that, that fixed it!!!
