Yes as said in the above comment you can make use of signals.

Give this a try,

Create a signals.py file in your app directory.

# signals.py
from django.db.models.signals import post_save, post_delete, pre_delete
from django.dispatch import receiver
from .models import AppConfig

@receiver(post_save, sender=AppConfig)
def log_appconfig_update(sender, instance, created, **kwargs):
    if created:
        action = "created"
    else:
        action = "modified"

    print(f"AppConfig {action}: {instance}")
    # Write Your Logic Here

@receiver([post_delete, pre_delete], sender=AppConfig)
def log_appconfig_delete(sender, instance, **kwargs):
    print(f"AppConfig deleted: {instance}")

then register the signals in your apps.py

from django.apps import AppConfig # don't confuse with models.AppConfig

class YourAppConfig(AppConfig):
    default_auto_field = 'django.db.models.BigAutoField'
    name = 'your_app_name'

    def ready(self):
        import your_app_name.signals

With this setup, every time an AppConfig instance is created, modified, or deleted, the corresponding message will be printed to terminal.
