Transfer decks to new Android Phone

Hello all. I just got a new Android phone and installed Forge. Now I'd like to transfer my Custom decks to it but I can't tell where Forge is installed or where the data is on my new phone. On my old phone (Samsung Galaxy J7) I can see the Forge directory. But I don't see it on my new phone (Samsung Galaxy A23 5G)
I've tried googling the answer but I only got a thread discussing how to do this on PC.
So is there a way other than trying to import the decks one by one? Thanks.
