I created 2 Omnistudio orgs to make a POC using the link https://trailhead.salesforce.com/promo/orgs/omnistudiotrails, but the email that arrives to verify account sends me to login page, but I don't have any password set yet. If I try to reset the password, the page asks a secret question that I do not have set either, so how am I supposed to know? How can I solve this problem?
