How to define global key binding for `C-c >` and `C-c <` using `defhydra`

Question

I am trying to apply following solutions's key binding to overwrite all mode's key bindings for C-c > and C-c <.

---

From the answer for Can we do C-c > and > and > to continue indentation:

(defhydra python-indent (global-map "C-c")
  "Adjust python indentation."
  (">" python-indent-shift-right "right")
  ("<" python-indent-shift-left "left"))

which works for the python-mode; but it does not overwrite into the global bindings and such as in shell-mode, its bind remain as to sh-learn-line-indent.

Is there any way to force to overwrite the key binding for C-c > and C-c <?

I have also tried following with the help of (https://emacs.stackexchange.com/a/68029/18414), which did not work:

(with-eval-after-load "sh-script"
    (defhydra python-indent (sh-mode-map "C-c")
      (">" python-indent-shift-right "right")
      ("<" python-indent-shift-left "left"))

Update:

Since you're using a Hydra, I think the best way to do this is to create a minor mode, and then define the hydra in that minor-mode.

Start by creating your minor mode as described in this answer.

Then you just need to define the hydra in the mode-map for that mode:

(defhydra python-indent (my-mode-map "C-c")
  "Adjust python indentation."
  (">" python-indent-shift-right "right")
  ("<" python-indent-shift-left "left"))

Once you've run all this code, you can turn on my-mode, and you should have access to your keybinding in all buffers.
