New Minecraft UI blocks Export World option on mobile (Bedrock 1.21.80)

I am using Minecraft Bedrock Edition version 1.21.80 on my mobile device (Vivo Y15C, Android). I downloaded the "Export World" mod/feature to save and back up my world, but the new UI blocks or hides the Export World button completely. I can’t find or use it, and this is very frustrating because I want to keep my world safe.

Please fix this issue or bring back easy access to the Export World/Backup feature in the new UI for mobile users
