The following code highlight an equation from the frame to be manipulated in next slides.

\setbeamertemplate{navigation symbols}{}
This is an example

                \tikzmarknode{B}{f(x)=\int_0^x g'(t) d t}
    \begin{tikzpicture}[overlay,remember picture]
        \fill<2->[opacity=.9,black] (current page.north east) rectangle (current page.south west);
        \fill<2->[rounded corners,fill=normal text.bg] ($(B.north west)+(-1cm,1cm)$)rectangle($(B.south east)+(1cm,-1cm)$) ;
        \node<2-> at (B){$\displaystyle f(x)=\int_0^x g'(t) d t$};

From slide 2, I have a black-transparent screen on the slide and a white portion of it containing my equation. In slide 3, I would like to move my highlighted equation around the page using animate package. I have recently asked a similar question, but that solution is only for the first slide. Moreover, it does not take into account the tikzmarknode.
