refund

I purchased the Q1 2022 DLC pack, but did not initially realize it was in my copy of the game the first time, and accidentally purchased it three more times. Is it possible to get a refund for the three extra purchases?

I'm a beginner in this game. I bought Rfactor2 and bought Nurburgring Endurance Pack, Endurance Bundle, Track Expansion Bundle on impulse. Can I refund items? I think it's been less than 2 hours since I bought something and played games.
