On my keyboard, there's an arrow pointing to the right like this: ">" in the top left corner.

When I click that it opens up my toolbar which has the microphone symbol. If I click that it opens the google microphone and that's as far as I want to go as I don't use voice to text ever.

If you don't see that symbol, you may need play with the settings but I wouldn't have enabled it purposely so it should be there by defaul.
