BigBlueButton Screenshare Chrome Extension
By default Google Chrome does not allow sharing of your computer screen. In order for the WebRTC Screenshare to work in BigBlueButton on Google Chrome, you need to whitelist your domain(s). This way Google Chrome will permit sharing your screen.
Everyone who is planning on sharing their screen in Google Chrome on BigBlueButton 2.0 using WebRTC will need to have an extension added. This set of instructions indicates how to whitelist your [institution's] domain(s) and publish the resulting extension to Google's extensions store.
In most use cases, a presenter will only need to add the extension from the Google Chrome store once. BigBlueButton administrators will need to create such
Instructions for presenters
Just add the Google Chrome extension provided from your institution to your browser. It should look like https://chrome.google.com/webstore/detail/bigbluebutton-screenshare/

"externally_connectable": {
"matches": [
"*://*.bigbluebutton.org/*",
"*://*.YOUR_DOMAIN.com/*"
]
Bump up the version of the extension in manifest.json and save all files.
Navigate to chrome://extensions/ in Google Chrome. Enable 'Developer Mode' via the checkmark. Remove any existing versions of this extension. Select Load unpacked extension... and navigate to the folder containing manifest.json
If you are able to use this unpacked extension and it is working correctly, it is now safe to upload it to the Chrome WebStore.
