How I can use my extension in mBlock online version?


Hello mBlock community, I created a new extension in mblock Builder, but I can’t use it on mBlock online version. What I should do it for use it?
I download the extension, when I drag and drop the file into the mBlock online programming window, the program shows me the following message:
“File in wrong format”

Help me, please!
