     * #### What are capabilities?
     * Capabilities are features or functionalities that a device can support. We divided those capabilities into `front` and `management` capabilities.
     * This section is about front capabilities, which include features like handling serial ports, video and stream playback, and more.
     *
     * On the other hand, the `management` capabilities are features that are related to the application management, such as app upgrade, app version, and more.
     * To check `management` capabilities, refer to the `sos.management.supports()` method or [this section](https://developers.signageos.io/sdk/sos_management/#supports).
     *
     * :::tip
     * If you want to check specific capabilities, refer to the sidebar for the selected management section. Every section has its capabilities written in the description,
     * or check the **DisplayCapability** type in `supports()` methods. It has a list of all available capabilities for all platforms.
     * :::
     *
     * @param capability The capability to check for support.
     * @returns {Promise<boolean>} Resolves to `true` if the capability is supported, otherwise `false`.
     * @since 3.1.0
