360 Vr to YouTube

Hello friends,

I've finished editing my gopro 360 VR video for youtube with premiere pro. The video I've tried to upload only shows a small curved video in youtube. I injected metdata to the video as well. I thought I followed all the steps correctly in editing. I know there is something I am mising to do in premier pro to make the 360 video appear the way I would like to (The look all around effect). Please assist if you can. I'm using a mac mini catalina. Thanks,  Memo.
