Add Microsoft Repository to Satellite

i am currently looking for the best way to add this repository:

https://packages.microsoft.com/config/rhel/8/prod.repo

in satellite, without any bash scripting if possible.
Somehow i seem to fail at that task.
I checked my firewall and test with curl command and everything seems to work until I try to add new product and repository via Satellite dashboard
Thanks a lot in advance and kind regards,
Aviv
