I believe each app have it's own auth token which gets issued after login with MFA in this case. Each app you configure with conditional access with MFA will ask upon access! I think there are some services that share this token though..
You can lower the MFA requests though by configure MFA for trusted devices in the policy to bypass reauthentication for a chosen period, but this doesn't affect that you still have separate MFA prompts for different apps..
