How to test extension before submit,from producer portal to Adobe creative cloud application.

Hi,

I uploaded extension(ZXP) but not submitted yet in adobe producer portal,after this i went on my adobe Add-ons website i see my uploaded extension in preview mode, from that i acquired and installed this extension but i didn't get any update in adobe creative cloud application(CC2018). In CC2018 synch mode is on and i sign out and sign in many times still facing same issue. how to get update in cc2018 and test in my InDesign cc2018. I dont want to use any Extension manager or Zxp installer. it is possible ??
