I'm an admin for a small business and I want to run an Office 365 attack simulation training phishing test. According to the article below, I need either one of these licenses: Microsoft 365 E5 or Microsoft Defender for Office 365 Plan 2

I want to test all my users. Is it enough to provide the O365 admin (me) either one of these licenses? Or do all the users which I'm gonna test need either one of the mentioned license?
