Describe the bug

When navigating the transcript using screen reader, we will narrate:

"Bot said: Hello. One attachment. Sent at XXX. Press ENTER to interact."

But when screen reader is in scan mode, the ENTER is being captured by the screen reader.

Steps to reproduce

1. Talk to a bot via https://compulim.github.io/webchat-loader/
2. Send card breakfast to the bot
3. While in scan mode (CAPSLOCK+SPACEBAR), use SHIFT+TAB to focus on the activity with the card
4. Press ENTER

Expected behavior

It should focus on the card content.

We might need to change ENTER to something else. We should investigate how active descendants and focus works in other accessible compound UIs.
