Enabling webRTC in FreePBX-17

i wanted to enable a webRTC for extension so that i can use it in my custome built web based webRTC softphone. but i dont know why when i run the following command ,am seeing “webrtc :no” in the output. “pjsip show endpoint 1006”

my plan is to build a simple webpage that can allow agents to take phone call.
am working on asterisk 21 and freePBX17

FreePBX for WebRTC Might be required license. Best think ( i did that way too) used pure Asterisk. maybe you have to look at install Asterisk only.
