Request MFA from users after successful login

Hi. I have another app that requests MFA after the user logs in using the Login trigger action flow.

But I have a different use case and would like to know whether I can request the user to do MFA at a later stage after they have successfully logged in and already have an access_token?

The Machine to Machine flow use case is not meant for users. So I’m not sure which Action Flow would I have to use in this case?
