There was no single version released. It was only available as the album track.

 

The lyric video was released on 4th September 2019 if you want to use that as a date.

Thanks,

Because i'm making a playlist per year with order of single released date. But for this song i thought it was released as a single but look like not. So sadly i need to remove it :(

It depends on your definition of single.

Many don't get a single track release but they still class them as a single.
