Steps needed to switch from `kadira:flow-router` to `ostrio:flow-router-extra`

I did update to Meteor version 2.9.1 however the useraccounts:flow-routing package wasn’t updated and is still on version 1.15.0 (thus requires kadira:flow-router).

So my app starts but I can’t login as I still get the:

console.error("There is no route for the path:", context.path);

error.

I’ve checked the guide but useraccounts:flow-routing isn’t mentioned anywhere. Is there a new version that is managed by the community instead? This package wasn’t touched for 6 years it says.

Thanks in advance!
