1. You are using the old deprecated API of tokens. Use the modern [Connection API](https://docs.openvidu.io/en/2.26.0/reference-docs/REST-API/#the-connection-object)
2. Creating a Connection with the permisions to use filters is just the first step to actually enable a server-side filter. You must call the client method to enable it. Read the filter documentation: [Voice and video filters - OpenVidu Docs](https://docs.openvidu.io/en/2.26.0/advanced-features/filters/)
