Kibana embed dashboard: Error authentification

Hello,
I have a problem in my kibana authentification.
I use an embed dashboard for sharing to some others peoples.
But the problem is they cant authenticate when they use chrome.
the brower reload and redirect to the login page with error in console 5601/api/licensing/info:1 Failed to load resource: the server responded with a status of 401 (Unauthorized)
When i use firefoxe it's works perfectly.
My version kibana is 7.13

How is authentication configured? Are you using anonymous authentication?
