Good luck. Lol.

Developers for dolphin - UNA have come and go, and there is never a guarantee you will have an update for future versions of UNA. This is from over 20 years of experience in dealing with this platform (dolphin 5.6)

You have two options. Learn to code, or hire someone to code. Because if you use third party modules, you will, as ANY long term una/dolphin user can attest, you will eventually have incompatibility issues - which you may need to fix yourself.
