How to init my class for using _set_appearence_mode?

[Sayad-Uddin-Tahsin]

class MonitorWidget:
    def __init__(self, root: ctk.CTkFrame, db: dict) -> None:
        super().__init__()

def create(self):
        self.root._set_appearance_mode('light')

I want to use _set_appearence_mode for in order to change the theme for specific Frame which says requires initializing with super()! Using this code seems not changing the theme

This method seems working...
