Searchable Drop-Down List not working in MS Office Excel 2021 Professional Plus.

Hi guys!

Two days ago I ordered and installed the MS Office Excel 2021 Professional Plus. I ordered it solely because I saw a YouTube video about the new Searchable Drop-Down List.
Unfortunately, I noticed it isn't working at all, while in Office 365 it works like charm.
Did they actually included it in Office 2021 or not yet?

Thanks a lot in advance for the info!
