How to access user access logs for Dynamics 365 for Operations?

Hello,

We use D365 Operations and have a need to pull the user access activity data (login / logout date time) from D365 Operations into a 3rd party application.

I understand that these logs are stored in sysuserlog table (??) but when I query this table (through VS), there are no records. Does this logging need to be turned on?

Also, what is the best way to extract this data from D365 Operations, since we have no direct access to the db. I can think of the following but wondering if someone has thoughts on the pros and cons or if there is a better way?

1) OData: Not sure if there is a data entity for sysuserlog and has its IsPublic property as Yes.

2) Export the data entity to a SQL Azure database using entity export...
