I would first look at the release notes for R2022b, here:
But, perhaps even better, since you alredy posted the link for those "missing" functions, you would read what you posted.
In there, at the bottom, you would see that function was introduced when? In R2022b. The docs for a function always tell you at the bottom when it was introduced. Some really old tools will tell you only that it was introduced before some point, since they only started maintaining that database at some initial point.
If you use an older release, you cannot use code that was introduced at a later time. Nobody can give it to you either. Sorry. If you want that capability, you need the current release.
