Please consider supporting https://github.com/zerolfx/copilot.el, too.

codegeex is a better choice than copilot which is free and open source.

• codegeex vscode extension: https://github.com/CodeGeeX/codegeex-vscode-extension
• codegeex itself: https://github.com/CodeGeeX/codegeex-vscode-extension

@sawyerzheng Don't be biased. There are no reasons to support one and exclude others for lsp-bridge.

And codegeex doesn't have a package to integrate with Emacs, whereas both copilot and codeium have.
