Need help at setting button -> media library -> create recording -> start recording

Hi d2l guys

I am a freshman and new to the xSite, https://xsite.singaporetech.edu.sg/d2l/loginh/, I discover there is a recording function in xsite which is useful to use in my assignment (see pic 1 to 3 below), setting button -> media library -> create recording -> start recording,

And I have two burning questions to ask you:
1. What is the maximum length can I record before the recording is stopped and reset?
2. Are there any user guide and information on this function for me to use it properly and correctly?
