Trying to sync save games via rclone script, with the Post-run Script function

[Booo3]

I saw that im able to run post scripts, so i made a quick script to sync my save games.

Everything works when i run it outside bottles, but when i run it with the Post-run Script function i get /home/boo3/Games/SaveGames/sync: line 6: /usr/bin/rclone: No such file or directory am i misunderstanding something or is that not possible?
