@fatimaansari This does absolutely, 100%, not work, for any mediasites. The pip always opens, slightly offset from bottom right corner.
I don't see the point of having a pip-feature, auto-pip even, that does not care about where you like to position it between sessions. I mean, it does remember position and size as long as you don't close the browser. This would be such a tiny code-segment, to save and fetch positions, that I do not understand why it would be met with any resistance.
