Getting logins stores as leads

[KCabrera1]

I'm trying to add hubspot to a NextJS app, I added the script for the forms and I have a demo request form on hubspot as well, I'm sending this request as a post request to the integration API, this is working fine, I also go the hubspot initialization script in this view, and in the landing page in the "contact us" form, however, when a user logs in it gets stored as a lead in my DB, the initialization script is not in all the views, I even remove it before a components that has it unmounts, how can I stop the platform to store al logins as leads in hubspot?
