undefined method `hkdf' for OpenSSL::KDF:Module

In trying to run the web-push gem on JRuby 9.4.9.0 with jruby-openssl version 0.15.1, I get the following error:

/Users/mohamed/.rbenv/versions/jruby-9.4.9.0/lib/ruby/gems/shared/gems/web-push-3.0.1/lib/web_push/encryption.rb:29:in `encrypt': undefined method `hkdf' for OpenSSL::KDF:Module (NoMethodError)

Here's a link to the line that caused the error: https://github.com/pushpad/web-push/blob/537267741b8b8cdd4ecedeb3f2da82e1145566d8/lib/web_push/encryption.rb#L29

This does not happen in MRI 3.1.6 and openssl 3.2.0
