Power BI Embedded Token Not allowing me to get report by id

I'm trying to use the Power BI API to load a Power BI Embedded report into my custom web app.

I login against AD

And then use that token to access the report list using

https://api.powerbi.com/v1.0/myorg/groups/{{groupId}}/reports

Then use the report ID selected to generate a token and then request the report by id for the embedded details.

Token https://api.powerbi.com/v1.0/myorg/groups/{{groupId}}/reports/{{reportId}}/GenerateToken

https://api.powerbi.com/v1.0/myorg/groups/{{groupId}}/reports/{{reportId}}

Calling the reports URL above gives me 403 Forbidden.

I can't figure out what I'm doing wrong.

Thank you
