Change Form in the Bpmn-js properties panel with Form io

hello guys i am new to bpmn io, in fact i’m facing a prob in how to change the Form related to user task in the Bpmn-js properties panel and replace Form Key and Form Fields with a Form that i created using Form io

Please provide more context. What is that form io thing? What would you replace?

i have integrated form io to my angular application it allows me to create customized forms with drag & drop.
So i want to replace form field and form key in the properties form palette with a select of forms that i have in my data base which i created using form io or i want to figure out how to make the form key accept the key of the form created using form io.
My prob is i haven’t found how to change the fields of form palette .
