Talkback: cannot open activity if it has either completion or a button

If an activity doesn't have completion and it doesn't have any button (download, open, ...) it works fine with Talkback enabled. If the activity has completion AND a button, it works fine too. However, if it has completion and no buttons or it has a button but no completion the activity cannot be selected/opened.

The only way I was able to make this work with a button was changing the "button" to "a" and removing the aria-label from the icon inside the button. But then the button cannot be used.

I also tried adding a hidden button to force having 2 buttons, but it doesn't work either because Talkback ignores it.
