Can a Way of the Astral Self monk grapple with its Arms of the Astral Self?

In the Unearthed Arcana version of the Way of the Astral Self, the monk’s Astral Arms were treated as monk weapons.

Under that wording, the monk probably couldn’t grapple/shove with them because weapon reach and the reach of the character’s hand that could make the grapple/shove are different things.

That is, it’s hard to see how you could grapple with the end of a polearm, for example (through a lenient DM might allow a shove).

However, in the official release, the wording was changed then from monk weapons to unarmed strikes:

  • You can use the spectral arms to make unarmed strikes.

  • When you make an unarmed strike with the arms on your turn, your reach for it is 5 feet greater than normal.

Under this revised wording, it seems like the monk could grapple/shove with its Astral Arms.

But can it?
