Converting "The Marvellous Suspender" saved tabs

Given that "The Marvellous Suspender" is no longer supported by Chrome, I have lots of saved tabs with urls like:

chrome-extension://noogafoofpebimajpfpamcfhoaifemoa/suspended.html#ttl=How%20can%20I%20recover%20a%20lost%20run%20activity%20or%20offline%20sync%20using%20the%20Android%20app%3F%20%7C%20Stryd%20Help%20Center&pos=0&uri=https://help.stryd.com/en/articles/6879319-how-can-i-recover-a-lost-run-activity-or-offline-sync-using-the-android-app

Any tips on regex transforming these back into a URI that Chrome will actually open?

I think I can lose the `ttl=` and just keep everything after `&uri=`.

Which file(s) would I need to go through?   

Export / import tips?
