I have a form variable formKeyA defaulted as a process variable from input parameter and value is "my-key".
I try to edit the text of Text View of the Camunda Form with the following text following the example Text view | Camunda Platform 8 Docs like below

Hello my key is {{formKeyA}}
But just display as when I view it in task list
Hello my key is {{formKeyA}}
instead of
Hello my key is my-key.
How can display the process variable in Text View of Camunda Form?
Or it is not supported?
