Edge extensions -- chrome.identity API is not a good UX

I am developing an Edge extension that connects to a Google account. So far, I've managed to connect using `chrome.identity.launchWebAuthFlow()`, but the user experience is not good -- I am forced to reconnect every hour to retrieve a new access token. In Chrome this is not a problem because it supports `chrome.identity.getAuthToken()`, which handles token refresh automatically.

Is there a solution where the user doesn't have to reconnect their Google account every hour?
