I am trying to create a custom print service that I can upload into ArcGIS Online and use from Experience Builder for our staff to create "Event Layouts" showing Tents, Foodtrucks, trash cans, etc all clustered into one area and filtered down to a specific Event Name and Date. The basic Near Me Widget Export Templates do show all of the attribute fields associated with the features, but it's laid out in a way that it's really inconvenient for viewing, so I've been going down the rabbit hole of custom reporting layouts and print services.
One of the problems I've encountered is that many of these articles suggest that this can only be published to AGOL if you have an Enterprise License, which I do not. I've also seen limitations that this is not currently an ability in Experience Builder.
So my question is, is it possible to upload and use a Custom Report uploaded from ArcPro into AGOL without having Enterprise?
Here is some documentation that I've been using to create the report in Pro and prepare it for AGOL.

Hm, I've personally published mine to Portal and shared that to AGOL and used it within EXB.
