How to add the access Token to the query so the Recording URI link play the call recording?

We are trying to make the Recording URI link playable in a dashboard. We are followoing the instructions here: https://developers.ringcentral.com/guide/voice/call-log/recordings

But the part about adding the access token is not clear. Can anyone help me understand:
1 - Which access token should I use?
2 - How to actually modify the URL to be clickable from a dashboard to open in another tab.
3 - Can I do this in a Looker Studio Dashboard?

Thank you!
