Module WebUI for additional settings can be accesses at:

TOS4: http(s)://yournasip:port/modules/Nextcloud_okm/www
TOS5: click on Support & Help from app description inside the App Center

In case you have additional app installed

After any upgrade version is installed, after the upgrade is completed, within Nextcloud WebUI restore your installed apps: go to Application control >> Restore apps

During setup choose this shared folder on your NAS as example, to store your data: 

/mnt/md0/appdata/NextcloudData (TOS4)
/Volume1/NextcloudData (TOS5)
As in example above, use the full path in nextcloud setup (symlinks can cause issues as Nextcloud doesn't allow symlinks as default)

As from version 21.0.2 apc need to be enable in php.ini to run under cli

Go to module WebUI and from menu choose Configuration files >> Edit php.ini
Add this line apc.enable_cli = 1 at the beginnig of the file as below (if is not already there):

; configuring many of the aspects of PHP's behavior.

Add cache memory

After Nextcloud is configured, add this line on nextcloud config.

'memcache.local' => '\OC\Memcache\APCu',

Optional add also Redis mem cached in nextcloud config.

'filelocking.enabled' => true,
'memcache.local' => '\OC\Memcache\Redis',
'memcache.locking' => '\OC\Memcache\Redis',
 'redis' => array(
     'host' => '127.0.0.1',
     'port' => 6379,
      ),

Here below some warning messages that you can encounter and a way to fix them
