Plugin state was disabled and not able to add new plugins

I have installed grafana with version 10.1.1 through helm charts. I am trying to add Amazon Athena Plugin, but it is showing installed plugins only and unable to add new plugins.

I added plugin in the chart and upgraded with below values. But in the pod it’s showing TLS certificate issue.
plugins: **
** - grafana-athena-datasource

How to enable and add plugins in opensource grafana
