I want to customize this visual for a specific use case. #104

Hi. I want to customize this visual for a particular use case. Here's what I want to do. Will you tell me if it's possible?

I've integrated html-content visual into my PowreBI report. I really like the functionality. However, what I'm wanting to do is to display my help content within this visual so that users can get help when they need it.

I have a published help site. Is it possible to only allow this particular web site to be shown in the visual? No other capabilities are needed b/c the navigation and help topics are already compiled to create the help website.

This solution would not be available as a visual in the AppSource store... it's a private solution I want to use b/c our help documentation is private and is only for users who have access to our PowerBI platform.

I appreciate your advice about how I could accomplish this.

Jim

Hi there, and I'm glad you like the visual. The non-certified version should allow embedding of remote content via iframes, provided that the site permits it from its side of things. The rules for this are documented here on the website.

There's not enough information about your architecture in your question for me to provide a complete answer. But, I'll provide what I do know and maybe this can help you determine if this might be possible.

If your documentation site permits access from sandboxed iframes with a null origin, then there should be no issues using the current AppSource version. However, if your documentation is restricted beyond a private authentication system, then this is a little tricky. The only supported authentication for custom visuals is via MS Entra, which is a very recent addition to the custom visuals APIs. You would need to create a visual with suitable permissions and add the authentication workflow. Assuming that you can authenticate, you would still probably need to check that your documentation site allows access from sandboxed iframes with null origins (which is how MS keeps custom visuals from doing more than they want).

If your use case is to display a single site and you were prepared to make a private build, it might be easier just to make a really basic custom visual that displays your target site in an iframe, without any of the other logic around it. You would still need to consider the Entra ID/authentication and whether your documentation site's configuration would permit the embed, but this would provide easier maintenance for you.
