Extracting Values from a Custom Object Field - Velocity Token

Hi guys,

I want to add in a customer number into a customer onboarding email, that is part of a synced SF field in Pardot.

The number looks as following:

Only the part behind the '/' should be displayed in the email. Unfortunately the length of the customer numbers differs, so there is not a fixed position in the field to extract from. I think this can done using Velocity scripting ('extract after /'), but I would not know how. Any ideas on how to do this?

The token for this field is {{company.EAN/OAN}}.

Thank you,

Jaap
