@Saif Thanks for your patience on this.
Below are some of the call capabilities supported by Azure communication services refer to this documentation here for complete list.
Regarding the remote control feature I have checked with Azure Communication Engineering team on this and below is the feedback shared.
Currently there is no remote-control feature in ACS but you can build remote control using data channel on ACS (in beta).
Here is the Quick start tutorial on how to use/add data channel messaging in your calling app.
I would suggest you raise a feedback request here. Our product team will review and implement it accordingly.
Feel free to reach back to me if you have any further questions.
