Communication with students

I've just finished teaching a course on computational finance with 26 students. Under the current lock-down situation, Rstudio cloud has been a live saver. However, we ran into one issue, and I'm curious to hear how it could be addressed.
I'm referring to communication between the instructor and students (broadcasting a message to all students, or answering a specific question from one student). For one-on-one conversation, I can annotate a student Rmd notebook, but is there a way to communicate with all students? I see some Github/Rstudio combined solutions... Is this the best way to address this communication issue?
