Issue with API for file download (Zoho CRM with WorkDrive API)

I can successfully run the below endpoint with Postman for this and get the list of files"

https://workdrive.zoho.com/api/v1/files/v310z10cba41b41c54363afcff08f2730a0b4/files

Then I try this endpoint with the same authentication token:

https://download-accl.zoho.com/v1/workdrive/download/v310zf0b27cc29f5040c7bda64baaecca983a

And get this response:

{

"ERROR_MESSAGE": "INVALID_OAUTHSCOPE",

"ERROR_CODE": 401

}

My authentication scope is

WorkDrive.files.CREATE,WorkDrive.files.READ,WorkDrive.files.UPDATE,WorkDrive.files.DELETE,WorkDrive.teamfolders.CREATE,WorkDrive.teamfolders.READ,WorkDrive.teamfolders.UPDATE,WorkDrive.teamfolders.DELETE,aaaserver.profile.READ
