Editing Python files does not reflect changes

Hello. I created a python file inside a custom app, and the method is being used in the ERPNext by calling frappe.call. However, once I made changes in the Python file, it didn’t reflect the changes. I tried clearing the cache, building the app, and migrating. Still no luck.

I’m already in developer mode; I set it using the set-config command, though I’m not sure if that’s enough. Thanks in advance.
