To enable Icomplete mode for the minibuffer, type @kbd{M-x

@code{t} (@pxref{Easy Customization}).
You can also additionally enable Icomplete for @kbd{C-M-i} (the
command @code{completion-at-point}) by customizing the variable
@code{icomplete-in-buffer} to @code{t}. For in-buffer completion, the
@code{completion-auto-help} variable controls when Icomplete's display
of possible completions appears. The default value of @code{t} means
that the display of possible completions appears when you first type
@kbd{C-M-i}.
By default, when you press @kbd{C-M-i}, both Icomplete's in-buffer
display of possible completions and the @file{*Completions*} buffer
appear. If you are using @code{icomplete-in-buffer}, then you may
wish to suppress this apperance of the @file{*Completions*} buffer.
To do that, add the following to your initialization file (@pxref{Init
File}):
@example
(advice-add 'completion-at-point :after #'minibuffer-hide-completions)
