Hi Siup, this plugin does not add rewind controls. I Believe you may be using a different plugin, or commenting on native browser controls; or the WordPress defaults.
If it is the older wordpress styled plugin, then finding out more about media-element.js will help you with this. https://www.mediaelementjs.com/
Originally this plugin alters media-element.js to add playback speed controls, but it does not add any other controls to that.
In more recent WordPress (post Gutenberg after 2017), Media is provided by HTML5. We do not even add controls for those; and custom HTML has to be explicitly added; so I think this plugin does what you are asking for in those situations, of letting authors decide.
If it is custom-coding you are looking for. This really isn’t the venue. I Believe the link I provided above may help, but also reference documents on JavaScript API’s https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement may help, as well as learning HTML5, CSS & JavaScript somewhere like https://www.freecodecamp.org/
