How do I change layer size without changing viewport (canvas)?

Hi! I added data from an external .csv file to an array with a loop and created text objects containing the data. But to fit them on the screen and allow scrolling down I only found set canvas size.

But this changes the viewport and everything is shown at once and extremely tiny.

I tried scroll to and setting layer and layout scales but this does not seem to help. Is there no way to increase layout size to allow scrolling down without changing the viewport/canvas size?

Maybe you just want to enable unbounded scrolling on the layout?
