Joplin-desktop - appimage-exec.sh missing

I recently started receiving these messages when trying to run joplin-desktop:

/nix/store/a6jvhk554wcaaqsizvg16fqa1s3zxhfj-joplin-desktop-2.10.18-init: line 19: /home/user/appimage-exec.sh -w /nix/store/m6gakkjqqb00jfv94ypiy8czqnxw2062-joplin-desktop-2.10.18-extracted --: No such file or directory

I do not have the file appimage-exec.sh on my system. Should it be installed when joplin-desktop is installed?
