Does Gnosis Safe have a native way to validate it's own eip1271 signatures? I know that Gnosis Safe's can have contract accounts as owners and it will verify those signatures according to eip1271 but what if I want my Gnosis Safe to sign a message that will be verified by another contract?
Let's say that my Gnosis Safe wants to submit a limit order on an exchange like 0x that uses signed messages. Assuming that 0x checks contract signatures with eip1271 how would I mark that signature as valid in my Gnosis Safe? Would I have to add a module (or something similar) to enable that functionality?
