Facebook Ad Keyword Stats is not woking

I wang to get the ad keyword stats using Facebook API, the reference API docs is :

https://developers.facebook.com/docs/marketing-api/reference/ad-keyword-stats/

I used https://graph.facebook.com/v11/ad_id/keywordstats?access_token=alskfajslkfjdlasjfldjaslkfdjlaksjlfkslfkdlasfd

ad_id used: AD ID

alskfajslkfjdlasjfldjaslkfdjlaksjlfkslfkdlasfd using real token.

but I got an error:

{ "error": { "message": "(#12) Ads keywords stats is deprecated for versions v5.0 and higher", "type": "OAuthException", "code": 12, "fbtrace_id": "AUGEDqfoo-5VroAam7bYIWf" } }

if I use v5.0, it will get :

{ "error": { "message": "(#2635) You are calling a deprecated version of the Ads API. Please update to the latest version: v11.0.", "type": "OAuthException", "code": 2635, "fbtrace_id": "Ayp8vk9LmHaSb5hKWFFnY_B" } }

so what should I do ?
