How to install livewire-devtools under Chrome?

Hello,
In the console of my Livewire/livewire 2 / laravel 7 app I got error :
```
login?email=admin%40mail.com&password=111111:60 Uncaught TypeError: window.livewire.devTools is not a function
at login?email=admin%40mail.com&password=111111:60
(anonymous) @ login?email=admin%40mail.com&password=111111:60
livewire-turbolinks.js:31 Uncaught TypeError: Livewire.hook is not a function

```
I loaded and installed package from https://github.com/beyondcode/livewire-devtools
and selected it under chrome://extensions/
but I see erros buttons red: https://prnt.sc/vqgk51

and clicking on it I see error:
```

```
I reopened Chrome and reloaded Kubutu.

Looking at branch https://github.com/beyondcode/livewire-devtools/issues/6
I found some hints how it can be fixed:
1) In file package.json I added
```
"devDependencies": {
"eslint": "^7.9.0"
},

```
eslint line and run
```
npm install
npm run watch-poll

```with success

2) In my project I found 3 files :

- /vendor/livewire/livewire/dist/manifest.json
- /public/mix-manifest.json
- /public/vendor/livewire/manifest.json
-

but all these 3 files are autogenerated I do not know which file have I to edit as I read :
```
{
...
"permissions": [
"http://*/*",
"https://*/*",
+ "contextMenus"
],
...
}
contextMenus is missed in manifest.json

```

What can be the issue and how to fix it ?

Thanks!
