Using Private Key JWT method with NextJS

Hi Dan, I am wondering how can I build login page in my React application (literally with my react components) besides using Auth0.js V9? I have read a lot of doc with vary teches/sdk which are all calling loginWithRedirect function. I know that Universal Login page is recommended as security reason. But all the stack holder or boss would like to see their logo rather than Auth0 logo in their application. Yes, we can customise Universal Login page with our theme but that feature is not really handy and powerful for business users. I also tried Classic Login page, I managed to fully custom it. But how about Passwordless login page? It is rendered by Auth0 lock.show() function so that I can not customise it. Please help me out for this Password less login page followed by OTP code verification page. Thanks a lot!!!
