Add Drop-Down Meun Country Dialing Codes

Hi,

I want to add a drop-down with country dialing codes and country flags to Contact Form 7, as in the image here https://qsnapnet.com/snaps/xv766vcjuu3anhf

After checking in a Stackoverflow post, I found out this plugin here https://jackocnr.com/intl-tel-input.html available in Github here https://github.com/Bluefieldscom/intl-tel-input, but not sure it would generate the right code for Contact Form 7

Any advice is welcome!

PS: alternatively, a drop-down list with country name and dialing code (without flags) will do.
