No configuration found for 'c'

Hi!

I have install dap following this post, and trying to setup debugging for c/c++.
But after doing :DIInstall ccppr_lldb and adding
dap_install.config("ccppr_lldb", {})
to the dapinstall.lua config file, I'm still getting an error

No configuration found for `c`. You need to add configs to `dap.configurations.c`

How do I add the configurations for c?
