All of our themes are Compatible to WordPress Full Site Editor (FSE or Gutenberg). So in new versions of WordPress you will notice that you can find Customizer, Widget and Menu options. All options are moved to new full site editor.
This means everything is now blocks and blocks will help you update settings too. Like if you want to update logo the. There is site logo block. If you want to add menu then there is navigation block. And there are tons of blocks that are similar to widget but have advance options.
If you are from WordPress classic editor and theme background then it might be little bit overwhelming for you but eventually you will find FSE more comfortable and useful.
