Popup mode for regular web application (Express.js)

Hello guys, we saw the popup mode of the Lock V11. That is pretty cool and we want to implement it to our website. However, we are not using SPA. What we are using is Express.js + Pug. Is there any way to achieve it?
In Lock Configuration Options, we saw we can set the clicentBaseUrl to something else. If this is what we should do, what should I write in my Express.js code?

Thanks.

Hi @alvin,

Thanks for reaching out, and welcome to the Auth0 Community!

It doesn’t look like you should any issues doing it from a regular web app. The following resource will guide you through it.

Let me know if I missed something.

Thanks,
