Data Hooks On External DB Not Working

I have an external MySQL database connected to Wix via the Velo External DB Adapter. For a couple of tables here, I am trying to set up a couple of data hooks for any insert/update events using the Data Hooks functionality.

But, my hooks are not triggering. My question is:
Do data hooks (afterInsert, afterUpdate) work with External database connected using the Velo External DB?

If these do work, can someone please direct me to any reference material to help implement the same?
