I have a custom button within a custom object that was coded/made by Salesforce labs. The button works in classic, but it's not working as intended in Lightning. We need to make minor customization to the visual force codes in order to make this compatible with Lightning. Can anyone help with this? Or direct me to the right contact? Thanks!
