Get custom e-mail field via SOAP

Hi!
Please tell us how we can access the custom email field via SOAP or REST. The issue is:after adding this field to CRM, it becomes available in the address book module and the AOS_Contracts module, but it is not available through the SOAP service.We’ve checked the availability of a custom email field using the get_entry and get_module_fields methods, but the response did not contain any of this fields. The custom email field was created using the following articles: - https://developer.sugarcrm.com/2011/08/08/howto-add-an-email-address-widget-to-any-module/ and https://www.rolustech.com/blog/how-to-create-email-field-in-custom-module
We will be very grateful for your help!
