install extension login google

I tried to run composer require saleksin/flarum-auth-google command but it didn't work and got an error :
Could not find a version of package saleksin/flarum-auth-google matching your minimum-stability (stable). Require it with an explicit version constraint allows its desired stability._
How to install google sign in extension. Thank you
Composer.json on my machine:
require": {
"flarum-lang/vietnamese": "¹.8",
"flarum/approval": "",
"flarum/bbcode": "",
"flarum/core": "¹.8",
"flarum/emoji": "",
"flarum/flags": "",
"flarum/lang-english": "",
"flarum/likes": "",
"flarum/lock": "",
"flarum/markdown": "",
"flarum/mentions": "",
"flarum/nicknames": "",
"flarum/pusher": "",
"flarum/statistics": "",
"flarum/sticky": "",
"flarum/subscriptions": "",
"flarum/suspend": "",
"flarum/tags": ""
},
"config": {
"preferred-install": "dist",
"sort-packages": true

Looks like a not maintained extension. Try FoF oAuth instead.
