Is there a way of getting a log of successful User Sign Ins to SSO Applications?

A bit of background, we are currently working on making an integration with Okta and one of the pieces of information we are trying to retrieve are a list of successful login attempts to the various Okta SSO Apps. So far the general idea we had was to utilize the System Logs api and filter out events of the type user.authenticate.sso, however the issue with this approach is that it seems to register all the times an user clicks on any app tile and doesn’t take into account whether or not they successfully authenticate:

Are there any alternative ways in which we can obtain a log of successful User sign ins to various SSO apps?
