Or you can turn on developer mode on your android device, in my opinion this is better because you can play around with a lot of new features and don’t need a shitty 3rd party app.
if you are on phone/tablet you must go into settings and find the (Build Number) if you have trouble google it. then just tap your build number 5-10 times or until it says dev mode is on.
for ChromeBook it is a little bit more complicated so I’m sure you can find a YT vid about it.
