Google Hangouts got split apart[1] . For consumers, they created duo for video and Android Message (with RCS) for text (after briefly launching and deleting allo). For business, they created Hangouts Meet for video and Hangouts Chat for text, which rapidly got renamed to Meet and Chat.
In 2020/2021 Google Chat was been opened up to consumers [2]. Now Meet and Duo are converging, the last nail in the coffin for the separate consumer/business app idea.
