Trying to authenticate to contact center historical data with bearer token using power automate

Hello All
I’m have setup a server to server app and can successfully request a bearer token to use to get the historical data for my contact center. I think I’m able to connect but all it get is

“next_page_token”: “”,
“page_size”: 10

I’m connecting to

What would I be missing on this and does it appear to be authenticating?

This is what my postman setup looks like with the results.

Hi Nik,
Could you please check whether the necessary scopes (needed for making the historical data call for your contact center) have set up in your server to server app.
