The local internet page is not reloaded when I change the code

Hi, i am using streamlit and when I change my code the Internet page is not relaunch. I need to relaunch my python program with the instruction streamlit run 'my app.py'to have the updated version.
I even don’t have the relaunch button. I tried to change the option as in the screenshot but no update.

How can I have an update from the internet page when I change the code.

I am using :
Streamlit version 1.32.2
Python : 3.10.13
