Bing Chat Enterprise Preview with Office E5 license

Hello

I have seen that with my Office E5 license I can still access to Bing Chat Enterprise in preview. 

Could you confirm me that it will be available also for this SKU and not only for the Microsoft 365 E5? 

Or when passing to General Availability BCE won't work anymore?

In case it will continue to work I would like to spread the news trough the Company working on the adoption.

Thank you!
