Send "How-to guides" to your organization from Attack Simulation training

Hi Clare_Ouyang,

A bit off topic, but I hope you can help me out a little bit.
A few ago the option 'Select delivery platform' (as in your screenshot in your post) was part of starting a new simulation. However the option Teams in there was greyed out? When I try to start a new simulation as of now, the whole option 'Select delivery platform' has disappeared? On top of that overhere: https://learn.microsoft.com/en-us/microsoft-365/security/office-365-security/attack-simulation-training-teams?view=o365-worldwide
Is mentioned first: 'In organizations with Microsoft Defender for Office 365 Plan 2 or Microsoft 365 Defender, admins can now use Attack simulation training to deliver simulated phishing messages in Microsoft Teams'. 

But later on the page says:
'If your organization is enrolled in Attack simulation training for Teams Private Preview'

Could you please provide some clarity around Teams in Attack simulation Training?

Thanks!

Kind regards,

Tim
