Change Item description for stripe checkout

I would like to change my item description what is sent to stripe to read better

Currently is shows as “options: Outdoor, Indoor, Yes, Medium” and I would like it to show as “Entry Type: Outdoor, Indoor - Shirt: Yes (Medium)”.

I can work out which filter to use and what object I need to edit. I have tried setting that is “gform_stripe_session_data” but it does change the output that goes to Stripe.

Check also the filter gform_stripe_charge_description.
