GraphQL authentication in browser

As it was stated in recent discussions, there is some information which can only be requested through graphQL.
So I go to the graphQL endpoint of my personal demo server in my browser and I can enter my query in Banana Cake Pop which opens. However, when I execute my query I get an error:
"The current user is not authorized to access this resource."

My question is: how can I supply my authentication parameters for Banana Cake Pop?

Thanks,
Klaus

Hello Klaus,

to authenticate yourself log in to the server in another tab of the same browser.

Best, Sergiy

Thank you, Sergiy. Works perfectly as a HQ user.
As opposed to accessing it from my R code where I have to supply my API user credentials.
