"setCustomValidity in JavaScript." But what is the effect of that?

[batje]

The documentation about validation states:

"You may provide custom validity messages with setCustomValidity in JavaScript."

But all the examples have hardcoded or sections.

Is there a way to use the original Validation messages with Bootstrap?

It looks like this information should be moved to the https://getbootstrap.com/docs/5.3/forms/validation/#browser-defaults part, because it works fine then - not with the custom BS styles.
