Transferring Rocket League Cars to PC?

Back then I bought Rocket League on the Switch and the McLaren in the Nintendo e-shop. If I transfer the account to the PC, will I also have the McLaren on the PC or will items that I buy from the e-shop not be transferred?

With the EPIC Games Account, log into both platforms with the same account and then you can have them all transferred to the PC. I don't know about the e-shop. I mean, however, if the car is in-game in your inventory, it should be theoretically transferred
