I recently installed pCloud.
It shows up fine in my file manager and if I click the App Image, it starts and shows the applet in the sys tray.
Is there any way I can get to this stage automatically. I have tried to add pCloud to autostart, but it is not listed.
You should create a launcher for your AppImage in ~/.local/share/applications
A launcher is an executable text file ( a .desktop file ) which could look like :
Comment=pCloud online storage
I think once there is a .desktop file launcher for an app, it appears in the autostart list.
