Power Automate refresh dataset visual freezing when embedded in a SharePoint Online page

Hi,

I have the Power Automate refresh dataset visual/button on my PBI report, it works perfectly on PBI desktop and in the PBI web service website, but when I click the button from a SharePoint Online page where the report is embedded it simply freezes and does not trigger a flow run. It gets stuck on a static 'Triggering' icon with a refresh circle that does not move:

Not sure what might be causing this, any help appreciated.
