Dash has no attribute 'register_page'

Dash Python

I am getting the error of register_page.
App.py
dbc.Navlink([
html.Div(page[“name”],className=“ms-2”),
],
href=page[“path”],
active=“exact”,
)
for page in Dash.page_registry.values()
],
Page1
from dash import DCC,html
dash.register_page(name ,path=‘/vc’,name='Page1")

Page2
from dash import DCC,html
dash.register_page(name ,path=‘/sur’,name='Page2")

Error
Attribute error:type object ‘Dash’ has no attribute ‘reguster__pages’

Please tell me where I am doing a mistake

It’s this the complete code? The error message indicates a typo.
