This is a tough situation. I’ve done my practical exercises in two different ways in a similar situation:
- Signup with a personal email address for a free account and enroll in a Pro trial (click on one of the tier-restricted features then “start a 14-day free trial” below the Talk to sales button)
- Request access to you company’s sandbox. There may be similar concerns about disrupting sandbox work, but much less so than in the live instance.
Hope one of those works for you!
