How to say "I want to see A doing this"?


I want to say **" I want to see A doing this"** to my Japanese friend,

I know that

> これ = This
>
> やっている = doing
>
> 見たい = want to see

but I'm not sure how should I put them together?

I tried researching online and came up with

> Aさんがやっているを見たい。

but I don't think it is correct...

**Edit** YES the suggested question has a clear answer. Nevertheless, if you
are looking for a way to construct such sentences, you would not really search
"How to use の?" since it would imply that you know the nominaliser is required
in the first place? In this case, I think the question that should be
considered duplicate should be like "How to use の in the sentence?"




You can say "Aさんがこれをやっているのを見たい"

I want to see A = Aさんを見たい doing this = これをやっている A doing this = Aさんがこれをやっている
