Hi @misc, this is en internal transaction - internal transactions, despite the name, are not actual transactions. When two smart contracts "interact,’’ the product or consequence of this interaction is a transaction. However, that transaction does not exist on the ETH blockchain. They are like a byproduct of smart contract functionality (see the source: https://support.bitpay.com/hc/en-us/articles/360050782511-What-are-Eth-Internal-Transactions-).
The reason why you cannot see this transaction in Trezor Suite is the backend that is used. Trezor Ethereum Blockbook at https://eth1.trezor.io/ does not know internal transactions. We are considering adding it in the future, but I cannot give you any ETA when it could be.
