I am using form.io open source in angular, and I want to know how to make the forms in it with the form manager and store them and connect them with the mongodb to store the submissions or even the form schema, and how to make the src URL of the form to render it in another project

I know how to make the form manager by this link https://github.com/formio/angular/wiki/Form-Manager#overriding-pages but I don’t know how to save the form and save the submissions of it, and Is there’s a way to render this form I made in another project
