This action allows you to set a person to follow a designated entity. The "Entity To Follow" field is where you enter an
Entity Id or an attribute that contains the person or group to follow. This field supports Lava.
Additional Details
If you are trying to mimic what happens when a person follows another person (by clicking their photo), the Entity Type should be set to "Person Alias" and the Entity To Follow must be set to the followee's PersonAliasId.
In v13, we made this easier to do. When the Entity Type is "Person Alias", if your Entity To Follow attribute holds a Person (field type), Rock will automatically use the PersonAlias Id from the fieldtype instead of the usual PersonAlias Guid (which would not otherwise work). v13.0
