Question about Refresh rate

Hello, I have a question about dashboard refresh rates:
I am using Grafana v12.2.1, I have around 300 dashboards, and I’ve set the auto-refresh interval to 1 minute for all of them.
I want to make sure — does the refresh only get triggered when a client is actively viewing a dashboard? It doesn’t happen in the background when no one is looking at any of the dashboards, right?
I’m asking because I’m concerned about the load this could put on the server.

It is refreshing, when it is loaded in the browser.
