The below code worked for me:

#imports
from pyVmomi import vim, vmodl
from pyVim import connect
import ssl

#Use below code after fetching session clone ticket from "/vcenter/session/clone-ticket" API
    if hasattr(ssl, '_create_unverified_context'):
        ssl._create_default_https_context = ssl._create_unverified_context
    stub = connect.SmartStubAdapter(host="vcenter-fqdn/IP")
    si = vim.ServiceInstance("ServiceInstance", stub)
    content = si.RetrieveContent()
    try:
        user_session = content.sessionManager.CloneSession(session_clone_ticket)
        session_id = si.content.sessionManager.currentSession.key
        auth_manager = si.content.authorizationManager
        root_folder = si.content.rootFolder
        privileges = ["VcIntegrity.lifecycleSettings.Read","VcIntegrity.Baseline.com.vmware.vcIntegrity.AssignBaselines","VcIntegrity.Baseline.com.vmware.vcIntegrity.ManageBaselines","VcIntegrity.General.com.vmware.vcIntegrity.Configure"]
        result = auth_manager.HasPrivilegeOnEntity(root_folder, session_id, privileges)
    except Exception as ex:
        print(f'Something went wrong cloning the session {ex}')
