How to change ACE_CHANNEL_DEFAULT_EMAIL from my Tutor plugin

Hi
I would like to change default ACE channel to custom implementation.

Can I include the rows like below in my plugin yml file? In which section?

ACE_ENABLED_CHANNELS = [‘custom_email_channel’]
ACE_CHANNEL_DEFAULT_EMAIL = ‘custom_email_channel’

Looking forward for help
Thank you in advance

Hi,
Doing some research in tutor, I found that the ACE channel is set in “tutor.templates/apps/openedx/settings/partials/common_all.py” as follow.

Email

EMAIL_USE_SSL = {{ SMTP_USE_SSL }}

Forward all emails from edX’s Automated Communication Engine (ACE) to django.

ACE_ENABLED_CHANNELS = [“django_email”]
ACE_CHANNEL_DEFAULT_EMAIL = “django_email”
ACE_CHANNEL_TRANSACTIONAL_EMAIL = “django_email”
EMAIL_FILE_PATH = “/tmp/openedx/emails”

Then if I set in my project.yml new ACE channel as below it is ignored

openedx-common-settings: |
ACE_ENABLED_CHANNELS = [“custom_email_channel”],
ACE_CHANNEL_DEFAULT_EMAIL = “custom_email_channel”,
ACE_CHANNEL_TRANSACTIONAL_EMAIL = “custom_email_channel”,

Other custom settings in my “openedx-common-settings” like OKTA_URL are included.

Could anyone give me an advise how to solve my problem?
