I am trying to add an api call in the "Create Custom tools" and given the POST method api url and given all the information for the payload or body(which the api call takes as the input) and whenever i am trying to add the headers of this format: -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \ -H "Content-Type: application/vnd.amadeus+json" \ -H "X-HTTP-Method-Override: GET" \ and saving it, it is showing that the changes are saved, but while creating the tool it is showing("The tool cannot be created") and i have tried to create the tool with out the headers, then the tool is getting created , so once the tool is created i tried to save the header, then it is showing that the "changes are saved", but when i go to Phone numbers (user interaction button) and come to the tools button, the headers are getting disaapeared like there is no headers saved. how to over come this problem?
