Need roles to access VBCS BO endpoints alone without access to integrations/applications

Hi,

We have a requirement where we need to create users in OIC and provide access to VBCS BO REST endpoints to access them using VBCS excel plugin. The users should not be able to access Integrations and VBCS applications. The endpoints of VBCS BO alone should be accessible by the user. We need a role suitable for the mentioned requirement. Kindly let us know if any role or approach available to achieve the same.

Thanks!!
