Add right-click context menu to search on the web
When in a chat, I often need to research topics that we discuss. It would be very convenient to highlight a word or phrase, then right-click and "Search the web". Clicking on that would send that phrase to your default search engine on your default web browser. This feature is currently available in most other Microsoft desktop products, including Word, Outlook, and Edge.
You could take it a step further and add an option to search for the phrase in Teams as well.
