    In some webpages where there is a <canvas> element, when i tried every single methode of mking the browser bigger, the page bigger... I did found some methodes that will make everything big, but the I check the canvas element it's like it still the same resolution just got bigger, and in some cases it even stay in the same size. But when I try manual Keyboard shortcut Ctrl +, the page zooms in adn the canvas element get a good resolution even if its bigger (i don't know why, maybe it got reloaded in the backend). I also tried the built-in Keyboard actions in Playwright Python, but seems to do nothing I don't know why. So after that I used PyAutoGui to simullate the user clicking Ctrl +, but the disadvantage of this solution is the PyAutoGui will zoom in in whatever page your on, no matter if its chrome or no, so you need to stay on chrome when executing the scrapping code. Is there a reliable way to programmatically trigger the same effect as Ctrl + —specifically one that improves the resolution of elements—using automation tools like Playwright, or perhaps through browser APIs?
