It doesn't appear on blockexplorers as the transactions that you've created with Electrum conflicts with the two transactions above, for which neither signals opt-in RBF. The Electrum node that you were using most likely already dropped the transaction, given that the minimummempoolfee is currently bigger than 5 satoshis by default implementation. Blockexplorers might not be able to see it but it's fine as long as nodes are willing to relay it; not a big issue and nothing much that you can do at this point anyways, other than moving away from Blockchain.com.
