Hi @pbiembeded,

Your error is basically that - visuals run in a sandboxed iframe and are not permitted to export data. The only permission currently set is allow-scripts.

It is unlikely that MS will change this, but you can always make a feature request in the GitHub repo for the SDK. There is already one for something similar that you could probably add your voice to.

Regards,

Daniel
