# disallowScreenshare()

Revokes the screenshare permissions for the target user. The target user id is provided as a parameter.

{% hint style="warning" %}
This method only takes effect if [allowScreenshare](/reference/sdk/methods/allowscreenshare.md) was previously called for that user.
{% endhint %}

```javascript
sambaFrame.disallowScreenshare('9efc7798-a1a4-44bd-9d8d-532fe0feea9d');
```

**Sample use case**: \
Have a custom participants panel in your integration and want moderators to be able to revoke screenshare permissions for particular users. It will be mostly useful in webinar scenarios where particular roles do not have screenshare permissions by default and these permissions are granted and revoked on the fly during the webinar.
