Unwrapping TRC21 SRM to SRM - my address is invalid?


I’m trying to unwrap my TRC21 SRM to SRM. I’m using my SRM address as created on sollet.io. However, when I input this address for TomoBridge, it states that the address is not a valid SRM address. I’m confused as to why this is happening given that I am in fact providing a valid address (you can see it on the Solana blockchain explorer).

Maybe I’m misunderstanding something? Does TRC21 SRM unwrap to SPL SRM or ERC20 SRM? In which case, would I provide an ETH address? This wouldn’t make sense to me though and would be confusing given the prompt is for a SRM address.
