Will the closed beta work on tweaker?

I've been playing the Microsoft store version through the tweaker and was wondering if anyone knew whether or not the closed beta test would run on it?

The CBT will run in a different client than the regular game, so right out of the gate, no, you won't be able to download/play the CBT with the Tweaker. There is a chance that the Tweaker team might try to make it possible, but who knows if they will put the time in to do so considering that the CBT is only 49 hours long.
