The following packages do the trick:

(use-package idle-highlight-mode
  :config (setq idle-highlight-idle-time 0.2)
  (idle-highlight-global-mode)
  ;; :hook ((prog-mode text-mode) . idle-highlight-mode)
  )


(use-package symbol-overlay
  :config
  (symbol-overlay-mode)
  (global-set-key (kbd "M-i") 'symbol-overlay-put)
  (global-set-key (kbd "M-n") 'symbol-overlay-switch-forward)
  (global-set-key (kbd "M-p") 'symbol-overlay-switch-backward)
  ;; (global-set-key (kbd "<f7>") 'symbol-overlay-mode)
  (global-set-key (kbd "<f8>") 'symbol-overlay-remove-all)
  )
