Plug-in & Macro installation ONLYOFFICE

Hi girls and boys!
I would like to use some of ONLYOFFICE’s awesome plug-ins I’ve already tried out in their test version
I can’t find the plugin folder in the nextcloud/apps/onlyoffice folder on my Server to download and install the plug-ins the way it is described on ONLYOFFICE’s website.

Thanks for your help dudes!

What have you tried?

I tried out the Youtube and Symbol-Table Plug-in in Onlyoffices test version.
Is it possible that we don’t have access to those option if we use the integrated Version in Nextcloud instead of setting up an own Onlyoffice Server?

Using the integrated version allows me to access and edit documents.
