Remove Unity Icon from webplayer that shows 2 seconds after the game starts


I am wondering if it is possible to remove the unity icon that slides in from the right bottom side a few seconds after the web player finishes loading the game (see image below)

If I must have pro version to remove it can I just buy it for one month, build a solution and use that solution after the pro period expires or I must keep renewing pro version to use that build?

You can’t buy Pro for a month. You either buy it at $1500 for ever, or start a subscription for 12 months.
