No action on "Join meeting"

[thomas-mc-work]

Describe the bug

Sometimes after creating a room a click on "Join Room" doesn't open the conference in a separate Tab/Window as expected. I can then still join using the link that is created below in the chat.

To Reproduce

Steps to reproduce the behavior:

1. Create a Room in a channel
2. Click on the 'Join Meeting' Button

Expected behavior

Expected: Join the room in a new window, but nothing happens

Environment:

• Mattermost version: [e.g. v6.1]
• Plugin version [e.g v4.3.0]

Additional context

A failed request from the network tab of the developer tools (exported as Fetch command):

await fetch("https://mattermost.mydomain.org/api/v4/users/status/ids", {
    "credentials": "include",
    "headers": {
        "User-Agent": "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:106.0) Gecko/20100101 Firefox/106.0",

        "Cache-Control": "no-cache"
    },
    "body": "[\"\"]",
    "method": "POST",
    "mode": "cors"
});

Respone:

There seem to be two different issues:

• open the session in a new tab: that was my fault. My browser blocked the popups, so here is no issue
• the failed request: this one still persists
