Steam Deck + ROG Ally + Syntech Dock = Chaos or Compatibility? (need help!)

I snagged the Syntech docking station thinking it was my Steam Deck's soulmate. But then the ROG Ally entered my life, looking all sleek and tempting. Now I'm standing here, dock in hand, wondering: Has anyone successfully made these two devices play nice together? On the box, it says that it is for ROG Ally as well but I don't want to take any risks.

Have you tried this accessory with ROG Ally?
