You could buy a large PEI sheet in sticker form and put it directly on your glass bed. Removal with a razor shouldn’t be difficult.

Is your bed heated? If yes, prints will stick well to the PEI when it’s hot and pop off when it’s cooled down. I have an ultrabase glass bed on my i3 clone and that’s exactly how it works there. I also gave a similar experience with my Voron with a PEI coated spring steel bed.

If your bed is unheated you might still be in hard mode.

As a final thought, go hot and slow for you first layer. I usually bump my first layer by 5-10 °C, depending on the material, and print it at 30-40 mm/sec. Even though I could probably go faster I’ll take consistently in my first layer.
