How can I access (read, insert data) non-standard (custom) modules? I try to insert data to custom module and get an error response: {"code":"INVALID_MODULE","details":{},"message":"the module name given seems to be invalid","status":"error"}

I guess it's because I don't know how to set the scope to acces the module. Module, which I want to acces is called CustomModule2, but when I try to set is in the scope on generating a grant token I get an error

When I set scope as ZohoCRM.modules.ALL or ZohoCRM.modules.Custom.ALL I get the same error response. What should I do to get the possibility to send data to custom modules?
