Here are some ideas for things you can do to test the limits of ProtectLib:

Try changing the DOM through Inspect
Try pressing this button and noting the change to the text of the button: Button

Try calling the `changeButtonText()` or `changeButtonTextSource()` functions from the console

Try using the `.get()` or `.set()` methods with the `variable` variable

Try using the `fetch()` or `fetch2()` functions
