Hi @medik
As @RolandP already mentioned, this is an “e-ticket” of the SNCF company “TER Auvergne-Rhône-Alpes”.
On the website where you bought this ticket, you can check the details or ask for assistance.
I have found two sites to search bookings:
TER (only available in French)
https://www.ter.sncf.com/auvergne-rhone-alpes/order-consultation
SNCF Connect (available in English)
https://www.sncf-connect.com/app/en-en/trips/search
Hope this helps.
Best regards,
Daniel
