Electric Window, Driver's side - got a video here, what part do I need?

Hey folks just wanted to say sorry in advance if the answer exists elsewhere, and thanks in advance for any help.

There's a lot of 'play' in the driver's side window. When the window gets wound up electrically it isn't sitting right, I've tried to make it really clear in this video:

I've love some help Re: the right part to buy, and how difficult it is to install. Do I need a new power window regulator?
I just got this beast and it's done 454000 KMs (~282K Miles). I have done some DIY on the car including cleaning the hybrid battery fan which I didn't find too tricky. I don't know about the windows though it seems like a cramped work area and a precision job to get the window to move right. I'd appreciate any thoughts on: how to do it, how hard it is to do, whether to leave it to a pro etc.

Cheers folks

 

Awesome thanks Chapman.

Hi bisco, I'm not sure of the function of that hole, here's a better shot of it - cheers:

Just wanted to check in and say that this website helped me find part number: 69801-52070
I chose right-hand drive, the part number suits both NHW20R- (AHEEBQ & AHEEBW). A local wrecker quoted me $110 including tax for a used one, as usual I'm on a quest for a deal...
There's this one by HANSUN on Amazon for $11USD+Shipping. I can't find reviews of that specific one but generally HANSUN seems OK.

It feels like a good start ... but maybe someone here has some knowledge/insight/expertise Re: whether or not getting this one is a good idea. I welcome any feedback.
