Regarding providing Custom TOTP MFA in freeradius

Hi Team, I have recently been working and developing with the freeradius EAP protocol. I need to send access-challenge request with state and Reply-Message "Enter TOTP" inside of inner-tunnel of EAP-TTLS/PAP Protocol which will prompt the user to enter TOTP and send the access request again and will process and authenticate the user for MFA. I have gone through this solution <https://lists.freeradius.org/pipermail/freeradius-users/2019-February/094471.html> inside the authorize section of inner-tunnel but the EAP module sends access-reject when doing this change, Please guide me in the proper direction on how to achieve this in our environment.
