Form that creates new users and e-mail each one a temporary password

Hi Everyone,

I'm starting to plan a new project to intermediate settlements. The idea is to create an app with all the information related to a possible settlement between two or more parties and approximate them to talk about settlement points inside knack app. I will only have the e-mail address from each side and I'm planning to create an app with a form that will use the e-mail addresses that I have to create users inside the app for each e-mail address and than send to them an email message notifying those users about the possibility to discuss a settlement inside knack app. The parties will also receive a random password to access this restrict view.

Does anyone know how can I create this flow? Specially the creation of new users using forms, because the volume of this settlements discussions will be a bit high.

Thanks in a advance.
