Behead support with Hollow palm

I just had a question about the interaction between the new Behead gem and skills like Frenzy / Elemental hit that can be used unarmed.

The Behead skill gem says:

- Supported Skills have +(2–3) to Melee Strike Range
- Supported Skills deal (30–49)% more Damage with Hits and Ailments against Enemies on Low Life

- Killing Blows from Supported Strike Skills with -> (Melee Weapons)<- against Rare Monsters grant one of their Modifiers for 20 seconds

- 20% chance to refresh Duration of granted Modifier by up to 5 seconds when you Hit a Rare or Unique Enemy with Supported Skills
- Additional Effects From Quality: Supported Skills have +(0–2) to Melee Strike Range


Frenzy and Elemental hit are both Strike skills, so this should work?
But the Behead support gem specifically says 'Melee weapons' so does unarmed like hollow palm work with this (as it counts as dual wielding, but still unarmed?) or would you get the benifits except the monster modifiers?

unfortunately your fists do not count as "melee weapons"
