On-Premises Data Gateway (Sign in) Help Please

Hey I'm trying to use my business account email (Company A) with full Power Automate features to create workflows for an organization I work for (Company B).

Company B uses Office 2013...so I can't log into Power Automate with this work email address because it the license this organization have doesn't allow per user purchase for Power Automate

I installed On-premises data gateway and wanted to know should I use my (Company A) work email address or use (Company B) work email address?

Again Company A work email have full access to Power Automate and would be the email address I use to create workflows within Power Automate
