We need to write logs separately in a new file in our project folder. If we use Write to Log file, logs are getting logged in the studio file :Assist Edge_Studio which is very difficult to identify the issue faster on which sequence it is getting failed. As we want to log both success and failure for all sequence hence we need to maintain the separate file.
If you want log file to get generated at some other place you will have to change log file path in config file.
If you want to do your own logging then you can use activity Add Log field.
If you require more customization then you can raise an Enhancement request with Product Team
