How to use the @uppy/transloadit.COMPANION_PATTERN function in @uppy/transloadit

function addRemoteProvider (uppy, name, opts) {
  const Provider = remoteProviders[name]
  const providerOptions = {
    // Default to the :tl: Companion servers.
    companionUrl: Transloadit.COMPANION,
    companionAllowedHosts: Transloadit.COMPANION_PATTERN
  }

  remoteProviderOptionNames.forEach((name) => {
    if (has(opts, name)) providerOptions[name] = opts[name]
  })
  // Apply overrides for a specific provider plugin.
  if (typeof opts[name] === 'object') {
    Object.assign(providerOptions, opts[name])
  }

  uppy.use(Provider, providerOptions)
}

uppy
