OS: All
Build Version: 20230207.6
Regression: Not a Regression

Repro Steps:

1. Create one Python (Programming Model V2) project.
2. Create a function to this project, such as "HTTP trigger".
3. Check whether there is a "Provide a function name" option during creating function.

Actual:
There is no "Provide a function name" option when creating function for a Python (Programming Model V2) project.

Suggestion:
It would be better to add a "Provide a function name" option when creating function for a Python (Programming Model V2) project.

More Info:
There is no error if adding a "HTTP trigger" function to a Python v2 project (uncomment the commented code in function_app.py), but the below error occurs when debugging this project, we need to change the function name manually to unblock the debugging.
