In order to PUBLISH workflows, you will need to establish a workflow trigger and a workflow action. Without both, you will only be able to save the workflow, not publish it.

To mark a Conversation as Read/Unread or Archive/Unarchive it, users should select the Edit Conversation action. This workflow action allows for getting rid of manually marking conversations as read/unread or archive/unarchive once an event is triggered.

You can either mark the conversation with the contact as "Read" or "Unread."

Click on "Mark as unread" if you already opened the contact's chat but need to be reminded of the chat, it returns the notification pop-up back on the chat.

You can mark a chat as "read" even without opening the chat, especially for conversations you want to skip.

You can decide to archive or unarchive the contact.

You can archive (hide) a chat by clicking this.

You can decide to unarchive a contact chat and move it to the recent tab.
