Where is the /edx/app/edxapp/studio.yml file located in the Open edX setup?

I’ve installed Open edX using Tutor on an EC2 instance and now I want to create a custom theme to override the existing logos and default content. However, I’ve been unable to locate files like /edx/app/edxapp/studio.yml because all my code is running inside Docker containers. Can you help me find the correct locations for these configuration files or suggest an alternative approach for creating and applying custom themes in this setup?

Hi! This article will help you Changing the appearance of Open edX — Tutor documentation

But be aware, some ui of OpenedX use templates, and some use microfrontend apps. About modifying mfe appearance GitHub - overhangio/tutor-mfe: This plugin makes it possible to easily add micro frontend (MFE) applications on top of an Open edX platform that runs with Tutor.

I’ve created a new theme located at /home/ubuntu/.local/share/tutor/env/build/openedx/themes/mytheme, but the Open edX logo in the footer hasn’t been removed. Is there a way to remove it?

Additionally, I’m not receiving emails for password reset requests, or any other emails from the Open edX platform. Do I need to configure settings like SMTP for this to work? If so, where should I update these configurations? If not, what could be the reason for the emails not being sent?
