[HELP] how to keep session when reload browser after call

[genffy]

There is a scenario in our business: During a call, if the browser is refreshed or closed, and the page is reloaded (within a limited time), we hope that the current call can continue. May I ask how to achieve this?

I have read the source code and tried to operate through the instance on the session. However, all of these operations are after the newRTCSession, and it is not possible to initialize it based on some existing parameters.
