chaibronz Yes, in the list of programs of your bottle open the context menu of a particular program (three dots on the right), the second option from the bottom should be "Add desktop entry". However, despite the name of the action, the shortcut in my case appeared only in the start menu, but not on the desktop.
Ohhh, but as mirkrobrombin wrote, this option is not available in the Flatpak version, unfortunately.
mirkrobrombin, If you mean the strange path to the application (path/to/App.exe), I wrote it for example, in reality the path is correct and everything works correctly. So there's nothing to report here. Thank you for the nice application.)
