Disk usage is increasing with puppeteer - chromium installed using snap

I have installed chromium using snap install chromium on my Ubuntu server with Arm cpu because when I wanted to install puppeteer using npm it throwed errors, I set PUPPETEER_EXECUTABLE_PATH to /snap/bin/chromium and it's working fine. But my problem is that disk space on the vps is getting full, when the usage is really high (more than 95%), I do snap remove chromium, snap install chromium and reboot. After reboot the disk usage is normal again (around 35%). The disk has 50 GB. What is causing that? Aren't browser data removed when I close it using browser.close()? Or what could be the reason that this cleans the disk space?
