@keharper, thank you for checking. Actually, this feature is currently available only in PaaS. The SCP module has been released in versions 4.7.16, 4.8.29, and 4.9.4, but the SaaS update is still pending and is expected in the next 2-3 weeks. I'll let you know once it's available in SaaS.
After we update this badge for PaaS, I believe we'll be good to merge. CC: @cod40403
