Automatically integrate Collabora after installing Nextcloud
Using Nextcloud's `occ` CLI, it should be possible to enable an app:
```
www-data@roiling-zorse-nextcloud-58b848fcc5-c5x7l:~/html$ php occ
Nextcloud 14.0.2
Usage:
command [options] [arguments]
...
app
app:check-code check code to be compliant
app:disable disable an app
app:enable enable an app
app:getpath Get an absolute path to the app directory
app:install install an app
app:list List all available apps
```
