you can ask kindly to finish current work and then reload, with a popup or so…

Exactly !

On my side, I put app version in localstorage (or cookie) and I check if the current version is different (ex: 9.0.10 -> 9.0.11) then I open dialog to inform the user that a new version is available since his last visit and if he want to see the changelog or not.
