is wifi-ap module for Raspberry pi has been removed?

https://ubuntu.com/core/docs/stacks/network/wifi-ap/docs/basic-ap-setup

I was referring to wifi-ap documentation for raspberry pi setup. Suddenly when I am trying to refer to the document it is a page not found.

I want to know whether the module has been removed or was removed by mistake. If it has been removed I want to know what are the best alternatives for that.
