Clicking on the Share Url opens a window that can't acquire the mic or the camera

[juan-escribano]

Describe the bug
When creating a new meeting inside a channel you are presented with both:

• A Share url link of the meeting: clicking it will open a new window inside Mattermost
• A button reading "Join meeting": clicking it opens the BBB meeting in the default browser
  The problem lies with the first option, as the new window inside Mattermost will not be able to acess the microphone and the webcam so it renders it impossible to do anything inside the meeting. For the microphone I get this message (translated from Spanish, not the original in English):

There was a problem with your audio devices

We could not enable your microphone
When entering a call, accept all requests if you are prompted to use the microphone.
Check your browser and device settings to ensure microphone access is allowed.
Refresh the page and try again.

In the case of the webcam, it just can't be found.

To Reproduce
Steps to reproduce the behavior:

1. Click on the BBB icon to create a new BBB room
2. Click on the Share URL link to join the room
3. Try to turn on camera and microphone

Expected behavior
The microphone and the webcam being detected by the new window

Environment:

• Mattermost version: 10.1.2
• Plugin version: 4.4.0

Thanks a lot for your help!
