Navigating Domain Changes and Dust-Slack Integration Issues

Hi Dust team, I’m on a 2 week trial. We are transitioning domains due to a company name change at the moment. The email I used to sign up for Dust differs from the (old) email domain I’m using in Slack. I now can’t test the Dust-Slack integration. I can’t seem to update my email in Dust. Should I just invite myself at the other email address, make that user an admin and remove my original account (assuming that’s possible)? I don’t want to incur any charges (still in a trial). Thx.
