Autostart inconsistancy on MacOS

I start jupyter lab on MacOS with the following command in a plist file with launchd.

/opt/homebrew/bin/jupyter-lab --app-dir=/opt/homebrew/share/jupyter/lab --no-browser --notebook-dir=/Users/myuser/mydataapp.

That works in a way. But one function is broken: Export as latex. It produces a pandoc not found error.
Pandoc is installed and in the path and works properly. When i use the above start command in a terminal-window, everything works as expected.

My question: how to configure the plist or jupyter-config-file, so that the export function will work when i autostart jupyter lab with launchd?

I guess launchd does not pass all the paths?
Any hint would be appreciated
