Unique submission Id?

Hi – I’m currently using this plugin: https://www.ads-software.com/plugins/cf7-submission-id/
to create a unique id for each submission for a form.

It works perfectly, but it hasn’t been updated in 2 years.

So, I’m looking for an alternative way of doing this. Does anyone know of another way this can be accomplished? Another plugin or code perhaps? Checking here since this dev has many Add-ons and wondering if there is one like this?

Would greatly appreciate any insight you can provide.
