Bring my own COG

Hello!
I need help using my Cloud Optimized GeoTIFF on the platform.
Before I start, I don’t know about programming, so it is possible that when creating the code I made a mistake, although I copied and pasted most of it.
I have followed the instructions https://docs.sentinel-hub.com/api/latest/#/API/byoc
The only thing I don’t do is create the COG using GDAL, I create it using the “Raster Copy” tool of Arcgis Pro, but I follow the rest of the steps.
When creating the tile, the Sentinel-hub dashboard, asks me to bounding box … is this not included in the GeoTIFF metadata?
Also, I don’t recognize the S3 bucket file.

Thanks for the help.
