Using environment variables in trigger

[Jsalaz1989]

I'm trying to use an environment variable in a OneDrive trigger. I know some time ago the docs stated that only 3 trigger types could take env vars (I believe it was SharePoint, and some other two that were neither OneDrive nor Outlook). Nowadays the docs do not state such a limitation so it seems like basically any trigger can take an env var now.

However, my 'When an item is created in OneDrive' trigger doesn't open up the dynamic content. Some forum answers mention typing in "@parameters('MyVarName')" but if I do that, the trigger doesn't get triggered. If you peek at the code, you see "@@parameters('MyVarName')", ie. it has a double "@". If you omit the "@", then peek code reveals "parameters('MyVarName')", ie. it's missing the "@".

I've been waiting for a while to be able to use env vars in any trigger (or at least the most common ones) but it seems like that's not the case yet?
