I have 2 questions, given a transaction, is it possible to:
get a list of the signers that already signed the transaction?
get a list of needed signers?
Returning a list like the following:
- Signer A,
- Signer B,
- (Signer C, Signer D)
So in this case signer A and B are strictly required, and then either C or D must sign as well.
