Once one interaction ends there's no simple way to transition to another interaction. The user would have to scan a new QR code which might not be the best UX depending on use case.
Solution
Add an optional attribute on the callbackUrl response that allows the wallet to start a new interaction from the end of the last interaction
This is also better than the user having to scan a new QR code because it avoids an extra round trip to the server
