Ok, in this https://wap.ghcap.vip/ there is an "Introduction to the Platform" link that leads to the following site- https://www.ghcos.vip/, and I can see there are mobile apps of this platform
And try to see if you can find the location of this "friend" that introduced you to this platform. Where did you meet this "friend"? Social media online or mobile social media? If they are from mobile, you might be able to find "her" location as well. Many of these crooks solicit through mobile social media so if you are able to find "her" location, you might be able to find the crooks' location that way.
