Message class missing dlr_route paramater

[gfrobenius]

Documentation mentions a dlr_route parameter for obtaining the status of the sent message:
https://developer.flowroute.com/api/messages/v2.1/send-an-sms/.

In src/Models/Message.php I see no mention of dlr_route. Can we please get this feature added? I'm very new to Flowroute so I may be reading the code wrong.

Thanks!

This repo tracks the previous api version, which didn't have dlr_route. @bermudezmt is working on an updated SDK that does provide the dlr_route param.
