Microsoft 365 not asking for MFA while doing login

We built Single Sign-on feature through SAML. We are using AWS Cognito as Service Provider and Azure AD as Identity Provider.

In our application, a user clicks on Login with Microsoft button, and we redirect them to the AWS Cognito URL for MS 365 login. The login works successfully and the user is able to access the application.

I have configured an MFA device using this link https://mysignins.microsoft.com/security-info. But while doing SSO login, it's not asking for MFA. How to enforce MFA during login?
