Hi all,
I've created a trial environment and I want to create an event (for showing how it could look).
But when I press live this note comes up:

"no local Dynamics 365 Portals or Power Portal is available, whick means you must host the event website on an external server if you want to provide it. For details see https://go.microsoft.com/fwlink/p/?linkid=2085798.
How can I create an event like this:

In the trial environment?
