Authenticate Alert Rule that use Data Source with Forward OAuth

I am trying to authenticate my alert rule using a data source that uses forward OAuth as its authentication method. When the alert is evaluated, it receives a 401, because there isn’t a way to pass authentication when configuring the alert. The endpoint that the data source queries (Mimir, Loki, Tempo) requires a Bearer token, but the alerting engine doesn’t forward it. Is there any way to make this work? I’ve already checked the documentation and couldn’t find a solution.
