Does the UA Barbarian Path of the Beast Claw Add the Strength Modifier to Damage?

I was looking through the options for the 3rd level Path of Beast feature, Form of the Beast, and I noticed no mention for any damage modifiers on hit.

Claws. Your hands transform into claws, which deal 1d6 slashing damage on a hit. (UA 2020, Pg. 1)

In comparison to this, the Aarakocra race gives you the Talons, specifically mentioning the damage value + the Strength modifier.

Your talons are natural weapons, which you can use to make unarmed strikes. If you hit with them, you deal slashing damage equal to 1d4 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike. (DND Beyond)

I am curious about this, because in another question, people have asked about the claws in an attack action, referencing damage values to include the Strength modifier.

—- Take Attack Action —-
attack with Greataxe (1d12+2+STR)
attack with Claw (1d6+2+STR)
attack with Claw (1d6+2+STR)
(From Can you wield a Greataxe and Claws…?)
