To automate the process, you’ll need to install the Automation extension, then go to Tools > Automations
Create a new Automation Rule with the Order Placed Event
Add the Assign to staff group action, then open the added action to choose the group to assign to. You can also add conditions to meet before assigning to the group using the Order Attribute condition.
Bear in mind the auto-assign feature uses Laravel Task Scheduler under the hood, so you’ll need to set up your task scheduler.
