How do I make it so everyone who tries to go on my website gets a challenge page?

Hi, I’m not sure how to make it so everyone who tries to go on my website gets the challenge page. Could anyone help me out here?

Use “I’m Under Attack” for the security level in Firewall -> Settings

Doesn’t that trigger the captcha a lot? I just want the challenge page without the captcha, hcaptcha is a bit weird.

Under Attack is the Javascript “Wait 5 seconds” challenge page.
