connect two spike essential hubs to scratch

[w1ngedshadow]

Hello, is there any way to connect two spike essential hubs (or any other two devices at one time) to scratch link? previously it was possible by using s2bot with scratch 2.0

I did it for 2 PoweredUp trains.
What You need to do:

1. copy scratch-gui/src/lib/libraries/extensions/poweredup to scratch-gui/src/lib/libraries/extensions/poweredup2
2. rename all poweredup-* to poweredup2*- files
3. edit index.jsx and replace all "poweredup" strings to "poweredup2"
   4)copy scratch-vm/src/extensions/scratch3_poweredup to scratch-vm/src/extensions/scratch3_poweredup2
4. edit index.js and replace string return "'poweredup2';" to "return 'poweredup2';"
5. optional:in index.js constanst blockIconURI contain base64 encoded icon in png format. You can decode, edit, encode and replace It.
   7)edit package.json in the root folder
   insert lines

    "register:poweredup2": "node ./scripts/register.js --link -C --id=\"poweredup2\" --block=\"./scratch-vm/src/extensions/scratch3_poweredup2\" --entry=\"./scratch-gui/src/lib/libraries/extensions/poweredup2\" --gui=\"../scratch-gui\"",
    "build:poweredup2": "npx xcratch-build --module=\"poweredup\" --block=\"scratch-vm/src/extensions/scratch3_poweredup2\" --entry=\"scratch-gui/src/lib/libraries/extensions/poweredup2\" --gui=\"../scratch-gui\"",

and change "register" and "build"
to

    "register": "npm run register:legoble && npm run register:spikeessential && npm run register:legoremote && npm run register:controlplus && npm run register:poweredup && npm run register:poweredup2 && npm run register:duplotrain && npm run register:legopeach && npm run register:legoluigi && npm run register:legomario",
    "build": "npm run build:legoble && npm run build:spikeessential && npm run build:legoremote && npm run build:controlplus && npm run build:poweredup && npm run build:poweredup2 && npm run build:duplotrain && npm run build:legopeach && npm run build:legoluigi && npm run build:legomario",

8. If you do this after building and installing the extension, you need to do it (7) manually:
   edit file scratch-gui/src/lib/libraries/extensions/index.jsx and add after extensions.unshift(poweredup);

// Injected for extra extension poweredup
import poweredup2 from './poweredup2/index.jsx';
extensions.unshift(poweredup2);

edit file scratch-vm/src/extensions/virtual-machine.js and add after CORE_EXTENSIONS.push('poweredup');

CORE_EXTENSIONS.push('poweredup2');

edit file scratch-vm/src/extensions/extension-support/extension-manager.js and add after builtinExtensions.poweredup = () => require('../extensions/scratch3_poweredup');

builtinExtensions.poweredup2 = () => require('../extensions/scratch3_poweredup2');

This is an example. I hid a couple of extensions that are not relevant to me.
