Implement v2 of Proxy protocol based on TCP

One of our service hosted in the on-prem datacenter and it requires to forward the client IP address to the backend pool servers. So I would like to implement the v2 of proxy protocol based on TCP Layer 4 header using iRules.

I went through this link but it has only v1 implementation: https://devcentral.f5.com/s/articles/proxy-protocol-initiator

Appreciate the help in advance.
