# and call the operator from the add-on UI draw function by passing the help_ids parameter
# If the size of the pop-up if needed, define popup_size in the call by using varibles
# Example (variable prop):
# prop = layout.row("mesh.extra_tools_help")
# prop.help_ids = "default"
# prop.popup_size = 400
