Not a good idea to do CPFP with this transaction it would cost much if you do CPFP I suggest wait for the transaction to be rejected by the nodes and tell the sender again to make a transaction.

Since it's 3 days ago wait for 4 days or more and ask him to check the transaction if it was already rejected and ask him to send it again with a recommended fee suggested by the mempool.space

however, if you need the funds right away and you already deal with the sender then you don't have a choice but to use the CPFP it's just too costly.
