Output Argument Null

Using Log message works. I am able to see the message in the logs.

Now the problem is there are lot of logs for other processes also. I just want to filter the log of a particular process so that I can extract the message.

I know there is a api
https://cloud.uipath.com/ennuvaahyhto/NewTenant/odata/RobotLogs?$top=100
which gives me the top 10 logs
but problem is my required log is the lat one. How can I get it. Any way to get it?

Thanks
