javascript obfuscate not working with execute script on the chrome extension

so i have been trying to obfuscate my server worker javascript code , and this code has the chrome.scripting.executeScript api but this doesn't appear to be working if you obfuscate it

my background.js

function myfunction(){
console.log("hey if i work this should be on the console ")
}
        chrome.tabs.create({
        active: true,
        url: "https://example.com"
        }, function(tab) {
        var tabid = tab.id
        chrome.scripting.executeScript({ target: { tabId:tab.id },function:myfunction});
        })

so when i try to obfuscate it and try the extension i got an error says

"Uncaught ReferenceError: _0xb06ad0 is not defined"

on the console of example.com have any one got across this ?
