Use of functions from bash-completion package in completer function

Hi,

I would like to use functions such as _filedir from the bash-completion package in the completer function. I have added bash-completion to the stage-packages but it seems that the functions are not available in the snap’s environment. In my completer script I am calling

_filedir

And end up with this error from snap run --command=complete

/etc/bash_completion.d/000_bash_completion_compat.bash: line 297: _comp_compgen: command not found

Is it possible to use such functions?

Thanks!
