sh: 1: exec: /home/e/.local/bin/textedit.py: Permission denied

[Eidonko]

Hello,
Many thanks for textedit-ly. Regrettably, I'm having problems with it.
I followed your instructions and launched ./install.sh
After launching evince and clicking on a note, I get "sh: 1: exec: /home/e/.local/bin/textedit.py: Permission denied"
I chmod +x'ed the file, but the problem is still there
I executed "sudo ln -s /etc/apparmor.d/usr.bin.evince /etc/apparmor.d/disable/usr.bin.evince" but problem is still there
I am running xubuntu (Ubuntu 22.04.2 LTS), GNU LilyPond 2.19.83, evince 42.3, gedit 46.1
Could you please help me? Thank you very much
Kind regards,
Eidon
