For future transactions, you can take a look at mempool.space and then see the lowest fee on the next block. If you want your tx to confirm immediatelly (at least around 1-2 blocks) then set a bit higher than that.

As of now, I'd say your transaction will likely get confirmed on the weekend. 2.2 is really low and prolly the next +20 blocks will have at least 5 sats as the lowest fee. So maybe just wait a bit more. Or just use RBF to bump up the fee.
