Solution

Google reCAPTCHA has a two-stage risk assessment. The Auth0 bot detection decides if the reCAPTCHA should be shown at all, and then the reCAPTCHA assesses how difficult of a challenge to present once it is rendered. For the second part, Auth0 does not have control over when Google shows the checkbox or captcha tiles.
