How to store crypto on the trezor

Ive currently got about half my crypto on a trezor one. When I bought the trezor, it said that is supported like a thousand coins, but I can only figure out how to put btc and eth onto it. I have other coins that I want to put on there, like solana, but I don’t know how to do it or if it is compatible. Anybody able to explain better how this is done? I have a bunch of crypto that I’m holding on exchanges because I don’t know how to put it into cold storage.
