Hi Team,

We want to incorporate a customized button into the Custom modules of our Zoho CRM account. We've observed that it's feasible to create custom buttons for both default modules and custom modules created using extensions. However, it's not possible to build a marketplace app with a custom button for Custom modules due to the lack of information about which customers have specific custom modules and fields.

However, if we develop a custom extension for a specific customer, would it be possible to access all the Custom modules using the Customer Developer account (Sigma)? Currently we observed that we can't access our ZohoCRM custom modules in Our Developer account.
