- Added using directives in `EnvelopeController.cs` for
`EnvelopeGenerator.Application.Envelopes.Queries.Read`
and `EnvelopeGenerator.Common.Constants`.
- Modified `GetAsync` method to use `ReadEnvelopeQuery`
instead of `StatusQuery`, updating the logic for
retrieving envelope data.
- Enhanced parameter description in
`EnvelopeReceiverController.cs` for clarity on
filtering criteria for envelope recipients.
