Your reservations are separate from the Railplanner app so there's no link between them.
The answer is simple, there’s no link. Reservations and the pass are seperate things. No need to look further.
In order to travel validly, you’ll have to present both the reservation (with the bar code you mentioned) and the qr-code generated by the rail planner app.
If you have other journeys planned with trains with obligatory seat reservations, feel free to share your itinerary. There are quite a number of ways to get your reservations, often a bit cheaper than booking the reservations made via Interrail/Eurail.
@BrendanDB and @AnnaB Thank you for your prompt responses, to wit: ‘There is no link. Reservations and the pass are seperate things.’ I can live with this.
And yes @BrendanDB, I certainly will use other-than-Eurail (DB, ÖBB, TrainLine, etc) sites to purchase seat reservations. I found the Eurail site to be rather complicated for that process.
My wife and I traveled all over Switzerland for two weeks last summer using a Swiss Pass. We had to get seat reservations for a number of the scenic trains we took. We definitely can manage having both pass QR codes and seat reservation papers.
For summer 2025, we will start with a few days in Prague before boarding trains. Then we will ride to Vienna and stay for several days of sightseeing and day trips (one of which will be a ride on the Semmerling railway). We repeat that plan of-rail to-cities (Melk, Hallstatt, Zell am See, ending Zurich) with day trips and scenic rail journeys like the Mariazellerbahn, Salzkammergut, Pinzgauer Lokalbahn and Arlberg. It should be fun!
Again, MANY thanks for your quick and useful reply.

You can travel on all scenic routes in Switzerland without reservations. You can't travel on the train called the Glacierexpress, but there are reservation free regional trains on same route. And the Berninaexpress even has reservations free carriages the same train, in addition to the reservation free regional trains on the Bernina route.
