Open public report in a lightbox not working

[TimH132]

I have a publicly sharable link for a report, which shows just fine when entered in a browser or as a clickable link on a webpage.
I want to open it in a lightbox using markdown. But when I do this, I get the error message
This content isn't available.
### [Geographic Map](https://app.powerbi.com/view?r=eyJrIjoiODllZmUxMWEtMWXXX9?lightbox=full)

Any ideas on how to get this to work?

Thanks

Thanks, the comments helped. You have to use an &.

This works.

It is essentially a modal window to view the report. ?lightbox=full is what you add to the end of a URL to show in the modal in the platform in which I want to show the report. So far, this has worked for any URL that can be added to an iframe. So not sure what is the issue with the Public link from Power BI Services.

As I said - that public link already has a question mark (ie it has its own query parameters).  You will probably need to encode that.

What's a lightbox?

Your URL has two question marks. That is not allowed.
