[MM-62001] Calls: switch tab on actions requiring focus

[streamer45]

Summary

For calls widget actions requiring focus on the main channel view (e.g., channel link click, showing screen sharing selection modal), we were not handling the possibility that the tab was something other than messaging. We fix this by switching to the expected tab.

Release Note

Fixed an issue preventing the screen sharing selection modal to show when the app was focused on a different tab (e.g. Playbooks, Boards)

Looks clean, thanks! And thanks for the great tests!

@DHaussermann Left some test steps in the ticket. Let me know if you need more info.

@streamer45 I have done a round of testing on this and the issue as described is resolved.
From the widget, the share is working and will flip to channels if needed to show you the screen share step. All other actions from the modal work and switch to channel context if needed (settings for example)

But I think something might be going wrong here. The widget aside, I see an issue where the screen share option is no longer working from the expanded view. Not 100% sure this was in scope but, I can't repro the issue on our production build. I don't just mean for switching tabs if needed. For me the share button no longer works from any tab.

Can you please see if you can repo this? (I have only tried on Mac)

• Install the build from the pipeline on this PR 5.11.0-develop.1
• Login to a server (I tried mutiple) and start a call
• Stay on the channels tab (optional)
• From the widget open the expanded view
• From the expanded view click the screen share
  Observed Nothing happens. The button seems non-functional.
  I don't have more details because I can seem to got to the expanded view in dev tools. I only see option for the main window and the widget. So I have no data from network tab or console.

@DHaussermann It sounds like you may be hitting https://mattermost.atlassian.net/browse/MM-62241, which was reported by @matthewbirtch as well during testing of #3253

I'll look at that separately since it's not related to these PRs as far as I can tell.

[DHaussermann]

Ah of course! Thanks @streamer45! This does seem like the issue I'm seeing. It seemed strange and as they both relate to screen share it seemed plausible it was from this PR 🙃.

[streamer45]

Absolutely!

Tested and passed

• Confirmed issue is resolved. Screen share from widget is functional and will flip to channels tab if needed
• Confirmed other options that need to flip to channels tab such as setting are also functional if you're on a different tab
• Regression tested other action in the widget that do not require flipping tabs

LGTM!

Issue with screen share via expanded view will be addressed separately.
