Missing Export and Import buttons on Chromebooks

I cannot find a button for exporting worlds. I am on minecraft bedrock for chromebook and I accidentally switched my storage from application to external in the minecraft settings. When I tried switching it back, it told me that external storage had changed location (idk what that means) and prompted me to check this page: https://help.minecraft.net/hc/en-us/articles/4414144725389

I was pretty spooked as it said something about cleaner applications that accidentally delete my worlds somehow, so I wanted to export them and move them into my google drive. However, when I went to my world settings (not loaded into the world), I found that the export button was not there. Idk if this is a glitch, or if the export system has changed, or if its even related to the fact that I changed from external to application, but the button is just not there:

**Yes, I've scrolled down all the way

**Also, I am not signed into minecraft on the device that world was on, and the version of the game was on v1.20.72, incase that info helps

Is there a way to fix this, or else an alternative way to export?

please reach out soon, idk how any of this technology works and as far as I know, the level of confusion im at rn would be the same in the scenario that my computer randomly decides to combust.
