Is there any place to configure the "http header"?

Hello there…

Just wanted to know if there are any ways to configure the Grafana’s request with custom header for the POST method? Because I want to let Grafana run on Cloud Platform, so there might be another security verifying on Cloud.

So, like, while I am adding a new Data Source on Grafana frontend, and then the frontend is calling the backend I would like to send another token within for those asynchronous requests. Therefore if there are any places where I can configure? Or only if I should change the Grafana’s codes?

Thanks for your advice…!
