the function about rich menu, which one I need to used when I want to set the image for a rich menu?

[ArthurTech123]

I'm trying to refactor my code from version 2 to version 3.

However, when I attempt to set the rich menu menu image,

I can't find a function equivalent to line_bot_api.set_default_rich_menu in the object of messaging_api.

The sample code on GitHub also does not show any rich menu-related functionalities.

Am I looking at the wrong object?
