Vim fn input completion not working

[abdulelah-tech]

Make sure you have done the following

• Updated to the latest version of blink.cmp
• Searched for existing issues and documentation (try <C-k> on https://cmp.saghen.dev)

Bug Description

As per the docs in the help section

<		The optional {completion} argument specifies the type of
		completion supported for the input.  Without it completion is
		not performed.  The supported completion types are the same as
		that can be supplied to a user-defined command using the
		"-complete=" argument.  Refer to |:command-completion| for
		more information.  Example: >vim
			let fname = input("File: ", "", "file")

but doing that has no effect

Screenshot:

Expected behavior

Auto complete suggestions should follow the configured completion in vim.fn.input
