Issue with fetching accounts and contacts from SAP sales cloud trial account

[hima_ods]

Hi,

I'm developing a connector to fetch accounts and contacts and its attachments from SAP sales cloud trial account. For this first I need to authenticate the user, for that I have created service key in SAP BTP Cockpit trial account. Now, I'm able to generate access token in postman, but not able to fetch contacts and accounts.
Below is the link for SAP sales cloud trial account:
https://my1000406.de1.demo.crm.cloud.sap/?sap-language=en-US&help-serviceLayerVersion=EXT&help-dataU...

and I have attached the service key generated from SAP BTP cockpit trial account.

Please help me to resolve this issue. Thanks in advance.
