The WHO ended it's public health emergency of international concern in 2023.
"Endemic" means that we can predict infection rates. This can happen one year after it has become stable at the earliest, so the fact that it's not called "endemic" yet isn't because we have have left emergency territory, it's because we need at least one year's worth of "stable" data to call it endemic.

So authorities declaring something to be endemic isnt exactly the same as a pandemic being over. They declared the latter, will declare the former with enough data.
