How to resize the floating window?

[RidaAyed]

How can I resize the floating window in order to see the folder's content?

Tried all four functions - while focusing on the floating window - to no avail:

(exwm-input-set-key (kbd "s-<C-left>") #'exwm-shrink-horizontally)
(exwm-input-set-key (kbd "s-<C-right>") #'exwm-enlarge-horizontally)
(exwm-input-set-key (kbd "s-<C-up>") #'exwm-shrink)
(exwm-input-set-key (kbd "s-<C-down>") #'exwm-enlarge)
