Paste graph from excel to a specific position in powerpoint slide

Hello!
I have an sheet in excel with 3 graphics, I would like to copy them and paste into the same slide in powerpoint, the problem that I am currently facing is that I am not able to paste the graphs at an specific position, so I am pasting the 3 graphics at the same place in the Powerpoint slide.
Here is the current code:

After posting in Reddit, I got some help from an user which changed the charts to be pasted as objects, would there be anyway to do this but maintaining the graph formatting from excel?
