Nextcloud Calendar with calendar_resource_management-master

Hey every interested and maybe helping person,

After the presentation of NC 22 and the possibillity to use ressources in the calendar app I installed an Nextcloud 22.1.0 on Ubuntu 20.04 TLS with apache2 and PHP 7.4.
I set up everything to find out, that the normal instanz of nextcloud don’t support the ressources yet. I found the app on github (GitHub), so i tried.
I unzip the files, set their rights and can see this app as disabled (in Browser as well on console with “occ app:list” command.

I tried to enable the app, but it doesn’t work.
In the browser i get the

Could not download app calendar_resource_management

and on console with

sudo -u www-data php -d memory_limit=512M ./occ app:enable calendar_resource_management-master

but get the response “App not found”

How can I enable this feature?
Someone an idea?

After i looked for some issued i found this:
the command

  sudo -u www-data php -d memory_limit=512M ./occ app:list

listed the App “calendar_resource_management-master”.
I looked than in

/var/www/nextcloud/apps/calendar_resource_management-master/appinfo

where the ID named “calendar_resource_management”.

so i tried

sudo -u www-data php -d memory_limit=512M --define apc.enable_cli=1 ./occ app:enable calendar_resource_management

and get the same

"Could not download app calendar_resource_management"

Found the solution to activate

The Zip file creates the folfer “calendar_resource_management-master”, but it has to be “calendar_resource_management”.

The solution:

cd /var/www/nextcloud

mv app/calendar_resource_management-master app/calendar_resource_management

sudo -u www-data php -d memory_limit=512M --define apc.enable_cli=1 ./occ app:enable calendar_resource_management

but how can i now use it?
