Hi,
You can inherit the create and write method of the main model, where you have added the many2many and achieve it. Inherit the write method, see the values writing into the db, if there is m2m field is triggered with write, perform your needed operation.

Hi,
Sure, you can do this by adding an onchange method to your model. The
onchange method will be triggered whenever the value of the many2many
field is changed. You can use this method to add or remove followers
from the sale order.
Hope it helps
