Conditional Access policy to require one of two MFA options?

We have Duo mfa configured and in use in our org. Duo works just fine as an mfa provider for Azure AD auth. We've been told my MS that a CA rule can be set to require Duo or MS mfa during auth. Has anyone actually tested this out and can describe the expected user workflow with this type of rule?

    @wick111 , Yes, it works. When you configure more than one MFA provider in Azure, all those MFA providers do get listed in the section Access Controls --> Grant, while creating a Conditional Access Policy.

    You can refer to the screenshot below for more info:

    I also stumbled upon the following article from DUO, which speaks about configuring the Conditional Access Policy in Azure For DUO. You can refer this article too.

    @soumi-MSFT

    Thanks for your reply. I was able to accomplish what you outlined but what i want to do is put option of using MS or DUO MFA in same policy. Someone at MS once told me you could do this successfully but i am unable to actually make it work in an OR manner for an end user. This is the config I'm seeking any additional insights on.

    If the CAP can evaluate two MFA providers, then it maybe possible just by selecting the both Duo and native Microsoft Authenticator.
