It is important to be able to manage the principle of the double signature of the legal representatives. Recipient Group should have an attribute on the minimum number of signers needed to consider the signing step fulfilled. Example: in a group of 6 legal representatives, at least 2 must sign. If I use 2 Recipient Groups with the same components, they all receive 2 emails from the system and the same person can sign the document twice (this is a problem to be solved)
