How to import ODATA service in Web IDE full-stack by using cloud connector

Dear experts,

I am new to the Fiori UI5, my requestments is to select my odata service under the service catolog. But now I cannot find any entry in the dropdown list. I can successfully import my odata service in the webide offline version, but not clear about how to configure it in the webide full-stack.

What I have searched.

I tried to follow the steps mentioned in below link, it seems sap cloud platform is changed, but integrate it under the BTP so I failed.

What I have done.

I have configured the cloud connector to conect to cloud foundry

Under the BTP, I maintained the destination but connection check failed. But somebody said it doesn`t influence..

There is no entry under the service catalog

I also found there is a subaccount in web IDE Trial. I guess it`s the neo environment. When I maintained the destination here, I can found it out in the service catalog. So I tried to create subaccount in the cloud connector but also failed.

So could you please let me know how to import ODATA service in Web IDE full-stack by using cloud connector?

Thanks in advance
