Get MFA token after login

Hello,

I’ve built an embedded login flow with a mandatory MFA for our application. I want to make a step-up functionality, but to send challenges and to get a new token with an extra scope I need a mfa_token. Is there a way to get a mfa_token without going to the universal login and re-authenticating? Like doing a call with the current access_token and then getting a new mfa_token?
