Is there a way in REST API to retrieve task's form field property back?

Camunda Modeler can let us set form field properties for tasks. I would like to use this feature to store some information for frontend input field rendering, e.g. inputtype=file for file upload selector.

Unfortunately, I found that the REST API /task/{taskid}/form-variables is not returing me such information and I have no other way to retrieve these information.

Any advice on how to get back these properties of task? Or any suggestion on how to store information for task that can let me retrieve them back through REST API?

Thanks in advance
