why palyer.offset is not a function

[hudi02]

my code like: player = videojs(document.getElementById('preview_video'), option, () => {}); const videoEl = that.$el.querySelector('#preview_video video'); player.offset({ start: 1000, end: 3000, restart_beginning: false, }); TypeError: player.offset is not a function?

No reference ‘offset’？ require('videojs-offset')
