my working theory is that the Hamas plan was essentially something like:

1. Break through the Gaza fence.
2. Spread out across the local region, taking hostages and killing settlers; bring the hostages back to Gaza.
3. Also try to reach places where Palestinians are being held in prisons in order to break them out and add fighters to the cause.
4. With this done, allow yourself to be pushed back into Gaza.
5. Israel puts Gaza under a siege that they might not be able to keep up if they have sent sufficient artillery ammunition to Ukraine; retaliate where possible against the siege.
6. Eventually, Israel is forced to move ground forces into Gaza, which is an incredibly difficult urban environment filled to the brim with people who not only hate you, but have nothing to lose by trying to kill you and destroy your vehicles; attrit enough Israelis to force a favourable peace. Additionally, Hezbollah and possibly Syria may distract Israeli forces in the north.

It looks like not continuing to be genocided while the entire world nods in silent agreement.

It's not likely to be successful but the alternative is continuing to be slowly genocided.
