you get the fees this way : https://stripe.com/docs/expand/use-cases#stripe-fee-for-payment and you could use that event to trigger that process

I'm using checkout sessions, should I add that to the below to the session params:
params.AddExpand("charges.data.balance_transaction")

I would get the PaymentIntent first. So you handle checkout.session.completed webhook. Then you call the API to retrieve the Session's payment_intent field. Then you can make the API call documented on that page.
