Zoom Team Chat API

Is there a way to use the method below to send a message which is a dropdown without having to do chatbot integration?

Send a chat message

POST /chat/users/{userId}/messages

Send chat messages to a user in your contact list or to a channel of which you are a member.
For user-level apps, pass the me value instead of the userId parameter.

To send a message to a contact, provide the contact’s email address in the to_contact field.
To send a message to a channel, provide the channel’s ID in to_channel parameter

Thanks
