How to use the @nstudio/xplat.stringUtils.classify function in @nstudio/xplat

const componentNames = options.components.split(',');
        for (let component of componentNames) {
          // using short name ("menu" for a component named "MenuComponent")
          // convert to fully best practice name
          const isShortName =
            component.toLowerCase().indexOf('component') === -1;
          let selector = `${workspacePrefix ? `${workspacePrefix}-` : ''}`;
          if (isShortName) {
            selector += component.toLowerCase();
          } else {
            const parts = component.toLowerCase().split('component');
            selector += parts[0];
          }
          componentSymbols.push({
            selector,
            symbol: `${stringUtils.classify(component)}${
              isShortName ? 'Component' : ''
            }`
