You can block a Kore.ai Messenger contact from the Profile tab screen or from the Manage Conversation screen.
On the Profile tab, tap Contacts, select the user you want to block, and then tap Block < Contact Name >.
On the Chats tab, select the chat that contains the user you want to block, and then tap the Manage Conversation icon. For one-on-one conversations (not available for group chats), you can block the sender of the message when you tap Block < User Name >.
Any message that the blocked contact tries to send to you is not delivered to your account.
On Desktop for Web or the Desktop App, click the Contacts on the top right corner of the Home page. On the Contacts pane, select a user, click the More icon, and then click Block.
