Present an ACDC from a multisig AID to a non-issuee recipient

[nkongsuwan]

Describe the bug
We created a multisig AID with 3 members and a threshold of 2/3. We were trying to present a LE vLEI credential to the vLEI reporting API (Sally) using the "Present" button in the Issue tab.

However, when one of the members clicked “Present” to Sally’s AID, who is not the issuee of the LE vLEI credential, the other two members did not receive any message in their mailboxes and were not able to join the presentation, i.e., signing the grant message to Sally. As a result, Sally could not receive a grant message with a sufficient number of signatures (2/3).

To Reproduce
Steps to reproduce the behavior:+

1. Create a mutisig AID with 3 members nad a threshold of 2.3
2. Issue an ACDC
3. Present the issued ACDC to an AID that is not the issuee of the ACDC.

Expected behavior
Once an ACDC is presented (i.e. granted) from a multisig AID to another AID, who may or may not be the issuee of the ACDC, /multisig/exn messages should be sent to other members' mailbox so that they could join the presentation by signing the same grant message.

At 2024-10-18T05:43Z, Arshdeep Singh said: When we click on the "Present" option, we initiate credential presentation by sending a grant using an exn message to the recipient we select in the popup that opens. The sender of the grant message is the identifier selected in the dropdown just above the table of credentials. If the selected identifier is a multisig identifier, the sender of the grant message is actually the local single-sig member identifier of the multisig identifier. As a result, the other members of the multisig identifier will not receive a notification to join the grant.
