Hi @luxemperor,
the Polygon chain is not natively supported in Trezor Suite. You need to use a 3rd party wallet MetaMask. Information on how to connect Trezor to MetaMask can be found here: How to use Trezor with MetaMask
You need to add Polygon chain to your MetaMask then: How to use EVM compatible chains with Trezor (Matic, Avax) - #2
Lastly, you need to import the desired token. Click “Import tokens” and enter the contract token address of STBU on Polygon chain (0xcf403036bc139d30080D2Cf0F5b48066F98191bB, it can be found on polygonscan.com)
