i don't see I don't see "Customized with power app" form

Hello everyone,
I am posting here because I am assuming that an O365 list is the same as a Sharepoint list.
I am trying to edit an O365 list form with power apps. This Form is saved but I cannot get it to be visible.

This are the taken steps:

1. Click the Create +New Button

1. Choose customize with power apps
   

    

2. When customized, click Publisch
   

    

3. Click
   

    

When I am back in List and click "+New" then I don't see the updated form.

When I return to Choose Customize with power apps, I see the updated form. So I am sure it is saved somewhere.

What extra step do i need to take to make the form visible when I click the +New button?

Thx,

Patrick
