How can I scale down a vector art comp inside another After Effects comp without losing quality?

Question

Adobe After Effects

There is the first composition consisting of vector graphics. According to the idea of ​​the video, this composition will be a laptop screen. There is a second composition with a room and a laptop on the table.
I want to overlay the first composition on the second composition, reduce it and substitute it in the laptop. That is, the second composition is the base, and on top of it the first composition is reduced. However, when I reduce the first composition, it loses quality, it becomes pixelated, although the composition itself consists of a vector inside. How can this be fixed?
