Electrum Wallet How to use "Child Pays for Parent"
You can't use CPFP to confirm that transaction. It's impossible for one to rescue a low fee transaction using CPFP, unless he/she has a private key of at least one ddress of that transaction's outputs (in your case, it's impossible, because you don't).

That transaction's receiver can do CPFP, if he/she wants.
