Deobfuscate code to make devtools working [closed]

I’m looking for a way to analyze a website that is blocking the devtools. I’ve found a script into the page that is obuscated and I’ve tried to deobfuscate it. At the moment I have this code but no way to revert it back

function check() {
                before = new Date()[_0x64f4('0x3')]();
                debugger ;after = new Date()[_0x64f4('0x3')]();
                if (after - before > minimalUserResponseInMiliseconds) {
                    document[_0x64f4('0x1')]('.');
                    self[_0x64f4('0x7')][_0x64f4('0x13')](window[_0x64f4('0x7')][_0x64f4('0xa')] + window[_0x64f4('0x7')][_0x64f4('0x12')]['substring'](window[_0x64f4('0x7')][_0x64f4('0xa')][_0x64f4('0x10')]));
                } else {
                    before = null;
                    after = null;
                    delete before;
                    delete after;
                }
                setTimeout(check, 0x6f);
            }

I’ve looked for some answers here but each situation need a different approach. Is there any way I can make devtools work on macOS chrome?
