Can anyone at OPNsense create a guide to setup Surfshark VPN?

I am having PFSense issues where the config page no longer functions after updating to 9.0 so I switched to OPNsense but Surfshark has an outdated guide to set up their service to work with OPNsense. I looked everywhere to see if I could install an outdated version of OPNsense like 22.x and then gradually update to the current version after I confirm that Surfshark works, but I cannot find an old OPNsense iso to download and try. So here I am with 26.7.3_8 and I cannot get Surfshark to work with it even with many hours chatting with their support. Help please.

Surfshark is like any other VPN-Provider, so probably no. Maybe use a desktop-client if *Sense is to hard for you.

I want a dedicated router so I don't have to install software anytime I connect the device. That is the whole point of this post. I would not be here if I wanted to install client software on devices. I am mainly looking for a way to install old OPNsense like version 22 or so.

So you now expect OpnSense CE (which is free) to invest in interoperability for Surfshark (which you presumably pay for)?
