"I'm unable to access the Agentforce Sales Coach settings in Trailhead. Is there a specific step or permission I might be missing? How can I enable or view these settings?"

They have updated the Trailhead to reflect the new UI. Now if we just go back into the trail head and follow the steps, we should be able to complete it.

If you have issues with the demo org, please disconnect it, create a new demo org and follow the trail.

Thats how I was able to complete it.

Trailhead が新しい UI を反映するように更新されました。Trailhead に戻って手順に従えば、完了できるはずです。

デモ組織で問題が発生した場合は、接続を解除し、新しいデモ組織を作成して Trail に従ってください。

私はその方法で完了できました。

In my playground org for the challenge "Enable Sales Coaching in Agentforce" the UI is quite different
