how get back the Appimage desktop integration dialog ?

I have an appimage in my workstation. after dbl click it asked me, if i want to intergrate it as desktop application. i answered “run once”. Then comes an dialog if i want to remember this answer, i clicked yes.
How i can bring back the question dialog?

You can try:

‘/home/user/Downloads/YourFile.AppImage’ --install

in terminal if you want to add the AppImage to your system.

For others reading this topic you must make the .AppImage file executable first before installing it to your system. You can do this by right clicking the file and selecting “Properties”. Now open the “Permissions” tab and put a tick in the box at the bottom which says “Program: Allow this file to run as a program”.
