I think that is done in the completion option after that where one selects
the file name or a directory based on ones' needs. This option as
I mentioned before  it was supposed to be for file types. If there is no builtin
list for file types(extensions) it might be sufficient to leave it alone
or have it call a list which contains "*" only. I have checked the completion
options for counsel-rg counsel-ag, consult-rg and they do it do it that way

With Regards
