Need to assign a task and send notifications to a team in workflow

There are multiple ways to assign an approval/activity to users. When an item needs to be assigned to multiple users, you can either pick all the users directly (when the list does not change for example), or pick a group/role (when there is one) or even define a workflow variable that picks all the required users based on conditions. Any of the methods will work. Email tab on the same properties pop up can be used to define the content.
