DAX function to give the "Name of File"

We might have multiple versions of a report published on Power BI services.
Ex: MyReport_v1.pbix, MyReport_v2.pbix, MyReport_v3.pbix and so on.

It is very difficult for us to identify which version we're using in embedding, e.g. SharePoint Embedding.
Now, to identify which version of the report we're using in embedding, we've to match the published to web link which we used for SharePoint embedding with published to web link of all versions of that report.

This is the problem, I'm facing these days.

One solution to this problem is to have a DAX function which will give us the name of the file so that we can put it on the report.
