We're building a chat with 100% custom UI using Smooch SDK's.
I have created a custom field for “App Market” which I would like to use to send metadata about the users selected market/country. The idea is to use this value in a trigger to assign tickets to different agents.
But I'm having trouble finding a way to set that metadata from the app using your SDK. We are using Sunshine Conversations for iOS and Android (Smooch)
The class reference for iOS only lists a getter for metadata.

Do we need to use the REST API  to set the metadata?

The REST endpoint I'm thinking of using.
