How to get number of users visited my R Shiny Dashboard?

Hello all,

I created a dashboard and publicized it last year. However, recently, I want to know how many users have been visited my dashboard. only lets me know how many hours it has been used. I know Google Analytics can track this but I don't know if they can capture how many users already visited before. I didn't use this before so that makes me concerned.

Thus, is there any way that I can check how many users have used my dashboard? I guess R Studio may have recorded this but I don't know how to get this number.

Much appreciate your answer!
