Cleavr installs Supervisor automatically for servers hosting PHP and Laravel sites.
You may use the Generic Port App site type to expose the local interface for Supervisor.
Follow the instructions to create the Generic Port App and set the port number to 9001.
There is one additional step you'll need to perform to expose the Supervisor UI.
SSH into your server, and edit the following file:
Append the following to the bottom of the file:
[inet_http_server] port=127.0.0.1:9001 username=admin password=password
Save the file, restart supervisor, and then access the domain you set up the Generic Port App with.
