How to use the @microsoft/sp-page-context.SPPermission.managePermissions function in @microsoft/sp-page-context

public onInit(): Promise {
    Log.info(LOG_SOURCE, 'Initialized LockItemCommandSet');
    // this where we check the permissions
    this._hasCorrectPermissions = this.context.pageContext.list.permissions.hasPermission(SPPermission.managePermissions);

    // setting up the pnp to work correctly with SPFx
    pnp.setup({
      spfxContext: this.context
    });
    return Promise.resolve();
  }
