Is there a way to generate a HOTP with time limitation?

For example, I want to get a HOTP that can only be used in 10 minutes.

Not TOTP cause it's possible that when users get the code there are only 10 seconds left.

    We can use the TOTP solution which can generate a one-time password every 1 minute, and when we got user’s input, we can check if there’s a TOTP generated in last 10 minutes matches it!
