i have some problems with yview_scroll and CTkScrollableFrame

hello
( I apologize because my English is not good :)
First of all, I want to thank you for this good library.
I have some problems with CTkScrollableFrame and yview_scroll in my project, this is part of the code:
In this code, I am trying to create a CTkScrollableFrame and like messengers, the scroll label stays at the bottom with each message label and displays the last message.(I'm trying to use a scrollable widget for users to display messages like other messaging apps, but I'm having trouble keeping the frame scrolled to the bottom when a new message is added.)

code:
# Chat box chat_box_frame = ctk.CTkScrollableFrame(bitchat_win, height=422, width=680, corner_radius= chat_box_frame.place(x=10, y=100)

when i get error:
chat_box_frame.yview_scroll(1, "units")

the error:
Unresolved attribute reference 'yview_scroll' for class 'CTkScrollableFrame'

AttributeError: 'CTkScrollableFrame' object has no attribute 'yview_moveto'
