Adding to that: building apps in electron that completely don't behave like you'd desktop apps expect to. Starting with sluggishness/high resource usage (Teams does little more than ICQ did back then, but needs more RAM than my entire PC had and it's still taking a second to think for each tab/chat change), but also just weird behavior of back buttons, that send you back to some seemingly arbitrary point within the app, but not back.

As much as I dislike electron being utterly overused, Teams is not just an electron app, it's a particularly bad electron app.
