How to Prove Ownership of a New Address to an Exchange?

I am planning to withdraw some sats from my exchange (Gemini) to my Trezor one. But they seem to have a very strict withdrawal SOP that requires me to prove the ownership of a public address.

The problems, as I see, are twofold

  • my trezor wallet has a few sats, but the specific address I created is brand new and I never received any fund there
  • I can send a few sats from my trezor device to the exchange, as a small deposit test, but I do not see a way to control the origin address. I mean, is not my trezor device just the collection of all addresses? I can receive in any of them, but can I send from a specific one of them?

So what's the way out here? Does Trezor 1 support this feature? Or have to resort to something else?

How to compute MAST commit bytes in bitcoin payment?

Image
The hash digests used to create the commitments are each 32 bytes, so proving that a spend of Figure 7-6 is authorized (using a merkle tree and the particular conditions) and authenticated (using signatures) uses 383 bytes. By comparison, the same spend without a merkle tree (i.e., providing all possible authorization conditions) uses 412 bytes. Can anyone explain how to compute 383 bytes and 412 bytes?
