How to run .bat from browser extension or html page?

Question

HTML

Good day. There is a task, launching a lot of executable batch files from a browser extension (mainly) or an html page (it will also do). Browser restrictions - Chrome, Yandex Browser. And if everything is very clear and has already been worked out with the execution of batch files of each other and all sorts of interlaunches, then there were big problems with the launch of batch files from under the browser (for me). I dug up a lot of information about this, I know that it ’s just not possible to launch anything, since all this has long been sewn up by browser developers. Running files only from the user's machine, the ability to change system settings is also available (without compromising external network security). Kindly tell me in which direction to dig, or if there is already a solution - throw it up, I will be overly grateful.
