Bootstrap 5 text BEFORE switch-checkbox (without extra addons/plugins)

I use Bootstrap 5 and I wand to use a switch-toggle.

I don't want to use any other addons, but only with bootstrap.

How to put a Text BEFORE the toggle switch.

This does not work:

<div class="form-check form-switch">
  off
  <input type="checkbox" class="form-check-input" id="site_state">
  <label for="site_state" class="form-check-label">on</label>
</div>

Anyone have an idea ?
