Let's imaging you have some text in the dictate-button powered text filed already, for example "I have some text" and you put cursor after "text". If you'd run dictation, the transcription would be inserted right after "text" without separation "I have some textdictated".
Good news is from now on the default integration scripts intelligently determine the need for blank spaces around the transcription, so your final text now would be "I have some text dictated".
Try demo to see how better the insertion is now https://dictate-button.io/
