No it doesn't.
To Hezbollah yes, to Hamas no. There is no anything 'rocket tech' of Iran in Gaza. These are all local designs based on artillery rocket designs. The know how is easy to attain for these. University students can build them. Hamas could build better weapon systems but it is impossible to import technology and materials needed for these. We don't need you (Iran) to build guided missile systems. We know how to. What we don't have is necessary materials and technology.
And if your Iran is providing so called 'major support', Hamas wouldn't plead with Muslim public and supports to donate via bitcoin to fund their military projects. Most of Hamas's military budget is from Hamas taxation of goods in Gaza and from popular support. We hardly get anything from Iran.
The armed wing of Hamas is using increasingly complex methods of raising funds via bitcoin, researchers say, highlighting the difficulties regulators face in tracking cryptocurrency financing of outfits designated by some as terrorist groups.

So? What does this have to with what's going on forum? Btw plenty of Arab and Muslim nations also spoke in favor in Gaza. You trying to paint Iran as some Muslim popular struggle champion is facetious. They brutalized Muslims in Syria. And they are doing big port deal with India which abuses Kashmiri Muslims:
...
...
India and Iran are close to striking a long-term agreement for operations at the strategic Chabahar port, with the matter held up only by differences on a clause related to arbitration, people familiar with the matter said.
...
The move for an India-Iran long-term agreement on Chabahar port comes at a time when China has been showing growing interest in investments in ports and other coastal infrastructure in Iran
