A telephony extension has been created in zoho crm for our cloud pbx web application.When logging in telephony extension using login credentials of our cloud pbx,if third party cookies are blocked in chrome browser incognito tab we are not able to login and an error is generated.The error is " 'sessionStorage' property from 'Window': Access is denied for this document." sessionStorage is used for storing login credentials for checking the user is logged in or not.

We need to be able to login when using chrome incognito tab even though cookies are blocked..please help us with this.
