Tableau Server: Is it possible to extract distinct number of guest account users over a specific time period from Tableau server repository?

I'd like to know the number of distinct guest account users over a specific time period. Is it possible to extract this information from Tableau server repository?

From my research, identifying distinct guest account user is not possible because the guest account has been designed to be an anonymous, non-login-based single account for all unauthenticated access. If this is true, is it possible to extract distinct remote_ip to get an approximate number? When I tried joining the tables ( _users with _http_requests) from PostgreSQL, I get NULL for remote_ip for guest account users. Not sure if this is expected.

At the moment, the only metric I can extract is the the total count of views (from views_stats) for my workbook of interest, but I'd also like to know how this number has changed over a specific time period, but I am unable to extract date/ timestamp data for guest account users. Could someone please advise? Thanks!
