External Login and Sign up buttons

Dear community,

on my website I would like to add two buttons for the users to login into the main application. The website it self has no Auth configured for authentication itself (Public WordPress). Currently I redirect the user to the APP which then bounces the users to the Auth page. As the main app is a WASAM it takes some time to load and is therefore not user friendly…

How can I do this to direct the users to the respective Auth0 screens?
Thank you
