OAuth embedding access token

[Jesper]

I'm building a multi-tenant MS Dynamics + MS Graph integration.
I'm getting an access token via Oauth and my Azure App in the connection I've made in Resources, but I cannot seem to inject the access token into the header of queries and APIs I call inside the app.
I do see the Access token exists in my query under Resources but when it comes to actually using it, I get this response:

{
"error": {
"code": "InvalidAuthenticationToken",
"message": "Access token is empty.",

I've tried multiple workarounds with setting up variables and different calls, but all returns with the same error message.
Is there a way where I can inject the access token in the header for my queries like "Authorization: Bearer {{ access_token }} ?

Hello @Jesper!

In your resource setup are you using the Custom Auth options?

You may need to define the token as a variable in the resource setup and then set the default Authorization Header in the basic header setup:

which gets the token from below:
