Unable to import Zip folder in Control Room

In reference to the topic- Hands On with the Next-Gen Process Composer (https://upskill.automationanywhere.com/hands-on-with-the-next-gen-process-composer/317859) , I was trying importing zip folder consisting pre build forms and bot same is attached, but after clicking import and selecting relevant zip folder nothing happens, I tried refreshing the folder where I imported the zip inside Control room, but still no files shown. I am using AA community edition. Please let me know if any solution.
