[Custom Components] Customize API request body with additional information

[Jananipradeep]

This is regarding the API call in the button click. The post-to URL option is available, but adding the API's desired posting structure is impossible here. Eg: On the API call, the post data is data:{} but if the API requires the structure form_data:{} or if we want to add any other property, it is unavailable.

I'll get this in front of our product team to consider possible enhancements to this particular option. For internal reference: FIO-9435

After review, we don't expect to resource a developer to investigate this in the near future but would be happy to review any contributions to enhance this component.
