How to detect a change in the deployed dash app on the user side?

We have a dashboard with basic HTTP auth running on an AWS cluster.

Given the following situation: the user has our dash app open and we make another deployment to AWS with a new frontend version. AWS makes a rolling updated of the pods, but we did change a frontend component, hence stuff stops working on the user side (rather unexpectedly). How can we notify the user to refresh his website to be able to use the new dashboard?

Thanks a lot,
