Script with automatic function in a site always doing the same process after a while

I'm looking for help in a particular function that I believe is easy but I do not understand the subject and if anyone can help I'm grateful. There is a website on the internet called BTCSPINER where you spin the spiner to mine satoshis. Only in this site you can put a SCRIPT by pressing the right mouse button click on inspect, go on console, paste the SCRIPT, press enter and after doing this the spiner turns on automatic. So what I want to do is a SCRIPT to put this automatic mode on another site. Placing the SCRIPT in the console window and pressing enter enter a function starts in automatic. I'm gonna explain. In the photo below where it has a number 0.00000351 it acts as a count that starts from 0.00000000 and increases. And at a certain time chosen by me I have to click on the floppy disk (shown by the arrow) and the count starts again from scratch. Anyway what I want, is a SCRIPT where I put a certain number as an example, that of the photo 0.00000351 (can be changed 0.00023351) and when the count reaches that number the floppy disk is triggered as if I had clicked on it. And with that the save function of the floppy will work in automatic. /9bJNG.png ">
