Markdown Formatting Assistant Plugin: 'trigger char' doesn't do anything

Things I have tried

I tried tot set the trigger char to different values, but none causes anything to happen when I use it in the editor (neither live preview nor source mode).
Obsidian language is set to Englisch, System and keyboard is German.

What I’m trying to do

I’d simple like to find out whether or not the inline editing is more convenient when using the trigger char and the autocompletion to format notes while writing.
