VerifyWebhook doesnt work

[wesleycremonini]

Version: github.com/GetStream/stream-chat-go/v7 v7.0.0

func WebhookIsValid(r *http.Request) bool {
	body, _ := io.ReadAll(r.Body)
	signature := r.Header.Get("X-Signature")
	return globalClient.VerifyWebhook(body, []byte(signature))
}

This always returns false, am I doing something wrong?
