IMAP login / sessions history not available

IMAP login / sessions history not available

Typically I'm unable to know where are users connecting from when using IMAP. If they login on the Web then it's visible on Device Sign-Ins, Active Sessions, Activity History, etc. This is a big security limitation. Is it a temporary problem? In the same field, Application-Specific Passwords show the creation date but don't show the last login time/agent header/ip address. For security review and revocation they are not so useful.
