I need to enable user screen sharing for my project. I used this example from the documentation - [Screen sharing documentation](https://docs.openvidu.io/en/stable/advanced-features/screen-share/#chrome-opera-firefox-safari-edge). It works great on my Mac with Google Chrome. Unfortunately, Firefox gives me this JS error:

> getDisplayMedia requires transient activation from a user gesture.

instead of asking for permission as Chrome does. Any idea, what can be wrong?

When some browser complains about “_something requiring a user gesture_” it means that the API you are trying to use is considered critical and for that reason it requires a user gesture to be the trigger of the action. For example, the click of a button. It seems that Firefox in this case is requiring that, but your application is requesting access to the screen sharing API (the initialization of the OpenVidu Publisher’s object) without a user gesture.  
If you encapsulate the Publisher’s initialization after a user gesture, you’ll see the problem go away.
