Live Chat icon not visible in Service Request Help desk

Hi Everyone,

We are enabling new feature Live Chat - Help Desk Live Chat and followed all the steps as suggested in document.

We are facing an issue where Chat Icon needs to be enabled via VBS, we have already copied the code and amended slightly as per instructions but still the Chat icon is not getting enabled when we preview the changes. Please see screenshots below :-

Code used :-

{"enableChat":true,"position":{"bottom":"10px","right":"10px"},"launchForm":[{"name":"serviceRequestNumber","required":false,"relaunchValue":"keep"},{"name":"subject","required":false,"relaunchValue":"clear"},{"name":"stripeCode","required":true,"relaunchValue":"default","options":[{"value":"ORA_SVC_HRHD","text":"Personnel/Personal Issue (HRHD)"},{"value":"ORA_SVC_ISR","text":"Business Issue (ISR)"}]},{"name":"queueId","required":true,"relaunchValue":"clear","options":[{"value":"300000411994321","text":"Benefits"},{"value":"300000411994324","text":"Payroll"},{"value":"TBD","text":"Complaint/Grievance"},{"value":"TBD","text":"Maintenance"},{"value":"TBD","text":"Expenses"},{"value":"TBD","text":"Other"}]}],"wcfsCdnPath":"https://ee.channels.ocs.oraclecloud.com/wcfs/23.10.0/wcfs-sdk.js","i18n":{"en":{"chatTitle":"LiveAgent"}}}
