Integrating with Nextjs

[FarukDev]

I am trying to display my content/page on my nextjs app, but i cant seem to find an updated documentation of builder that shows me, pls can you instruct on how to implement it?, i did but i am getting an empty/blank screen and when i logged out the content, it says null… i checked the docs, it asked me to create a page in the model, but on the model page, it says it is a legacy feature and i cant even create the page
