Thank you for contacting the Zendesk Support Advocacy team.

Could you please follow these steps to check if you can disable Messaging on your end: https://support.zendesk.com/hc/en-us/articles/5166855265690-How-do-I-turn-off-messaging-and-go-back-to-live-chat#:~:text=See%20the%20steps%20to%20turn%20off%20messaging%20for%20the%20entire%20account%3A
