How to add records in Zoho CRM to related list with custom function

Hello.

I am currently using Zoho CRM Enterprise.

After creating about 3 custom tabs (custom modules), I want to list them in the related list of custom tabs, but I don't know how to write custom functions.

Thing you want to do

A → B (Lookup)
A → C (Lookup)
B → C (← I want to display the related list here)

Please tell me the specific Deluge Script.
Thank you.
