UI Layer with Different Resolution

Hello! I’m currently making a game in Phaser 3 using PixelArt mode and a low 480x270 resolution, which is working very well when I scale it up to fullscreen. I would like to use higher resolution elements in my UI for readability and scale purposes, i.e. a normal monitor resolution such as 1920x1080. I’m imagining a layer above the Phaser game itself in which I can render UI elements. Is there a way to achieve this effect natively in Phaser, or will I need to create/render/update a separate canvas over top of the Phaser container?
