How to let kate see clangd

Help

I have kate installed as flatpak (26.04.2) and I’ve installed the runtime extension llvm21 for clangd. In the output field kate seems not to recognize it at all.
This is the error:
[12:13:56 LSP Client Warning] Failed to find server binary ‘clangd’ for language ‘c’

Please check your PATH for the binary

See also for installation or details

How to configure and fix that?

What does which clangd in a terminal window say?

Kate tries to find the lsp binaries on the host system so clangd needs to be available on the host system and in your host PATH.
