Browser-Based Remote Support Tool Needed

I'm in search of a browser-based remote support tool similar to Screen Connect, but without a chat session feature. The tool must provide full control access and be compatible with both Windows and macOS operating systems.

Key Requirements:
- Browser-based remote support functionality
- Full control access to remote systems
- Compatibility with Windows and macOS
- No chat session feature

Ideal Skills and Experience:
- Experience in developing or implementing remote support tools
- Strong understanding of browser-based application development
- Familiarity with cross-platform compatibility issues
- Ability to ensure secure and reliable remote access

If you have expertise in creating or setting up such a tool, I would love to hear from you.
