Upload mapping via Firebase CLI

[Lzk85]

Hi all,
I have CLI with version 11.0.1.
In docs i see that it possible to upload my app's mapping via CLI, but when i tried to do it i got message

Error: crashlytics:mappingfile:upload is not a Firebase command
Did you mean crashlytics:symbols:upload?

Is it not actual official docs? Or where is my mistake ?
