If those coins are not needed for you immediately, or you those transactions are for just testing purpose, then leave it as is. It will be confirmed when pools don't get paid transactions. However, if you want to make it spendable immediately then you need to go with the RBF concept of double spending. Or use CPFP method to send the transaction with a fee. My guess you just leave it as it is. It will be confirmed later without a double spend issue.
