Getting 403 errors in my PowerApps trial

I have imported a Solution, previously exported from a D365 enviornment into Power Apps 30 day trial. The solution comprises a number of unmanaged webresource components e.g. CSS, Jscript and HTML.

 

I’ve created a Portal form that attempts to pull in these components but all, except the HTML resource, are showing 403 errors, indicating authorisation problems.

 

Maybe there are limitations with the trial licence i.e. "Web resources are only available by using the Dataverse web application security context. Only licensed Dataverse users who have the necessary privileges can access them.”  I’m going to attempt to sign up for a community plan to experiment further...

 

As things stand, I can’t find any way to grant permissions for these components; does anyone have any suggestions?

A colleague sussed it:

Have a look at these docs and see if they help:

Web Resources (model-driven apps) - Power Apps | Microsoft Docs

The other alternative is in your trial license, if you go into Admin Centre you may have the option to contact MS support for this.
