I'm trying to add another MFA option (sophos authenticator or google authenticator), following this KB

https://docs.sophos.com/central/customer/help/en-us/central/Customer/common/learningContents/MultiFactorAuthentication.html

but i don't see (or found?) the option "Manage Login Settings"  to add another method ,i'm super Admin of my sophos central dashboard
