You seem to be in PSBT mode. For PSBT transaction the stages are unsigned, signed, finalized, broadcast. Since you are being prompted to finalize, the next stage would be to broadcast. Once broadcast, you should see it on block explorers.
This does make some assumptions based on what wallet you are using. If a Trezor or 3rd party wallet is using the word “finalize” in a way unrelated to PSBT, then I'm obviously incorrect.
