How does Insync work the first time we launch it?

Hi everyone!

I have just installed insync with a prime license and, until now, it is not syncing. I am not able to see my google drive files on my local folder attached to insync. Also, the selective sync option does not appear.

I have thought about some answers, but I could not confirm them here. One of them is because I have more then 200GB of file on my google drive and maybe it will take some time too see the selective sync option?

Could you guys help me to understand what is happening?

How long has this been syncing? Initial sync will take some time especially with a larger number of files.
