Gaming-focused discord clone Development

I'm looking for a Windows-compatible Discord primarily designed for a gaming community. The software should be based on an existing open-source project like Mumble or Matrix.

Key Features:
- Voice chat
- Text chat
- Screen sharing
- Ability to join voice chat groups
- Generating invite links
- Creating custom chat groups/servers, similar to Discord

Ideal Skills:
- Proficiency in Windows software development
- Experience with open-source software like Mumble/Matrix
- Strong understanding of voice and text chat software development
- Ability to implement server creation and invite link features
