How to display the value of $__rate_interval?

We use Grafana 8 together with Prometheus.
I created a dashboard and I use the automatically generated variable $__rate_interval all over the panels.
For visibility, in favor of other users of the dashboard, I would like to present the value that is assigned to this variable upon every refresh of the dashboard.
I couldn’t find any way for this small and should-be-easy requirement.
Could anyone suggest a way to do that?
Thank you very much
