Hi, I am drawing Feynman diagrams for various Higgs decay channels. There are two diagrams I am stuck on and there aren't many examples online. They are H→gg and H→Z$\gamma$

For the H→gg decay I had a stab at drawing the reverse of the gluon fusion diagram. Higgs decaying to two gluons via a top quark loop process. I am not sure if this is right.

As for the H→Z$\gamma$ could someone explain this decay so I can get an idea of how the feynman diagram should look? Thanks for any help.
