How to get HABPanel working?

Is there a tutor or explanation on the use of HABPanel in OH3?
How can i tell HABPanel to use the configuration on the server side?
I want to use a HABPanel in the cloud. Anybody any idea.?
There has been an older thread on this issue but it did not get an satisfactory explanation or resolution. Cant display HabPanel Ui via OH App - OH3 - #6 by DiegoDf
