Hmm how can I make I make tlauncher open with open JDK installed?

Been playing with my friends on our server and recently changed it into paper server, and noticed that it’ says to change the java ver to the openJDK ver.
My problem is that I use the tlauncher to open my minecraft, and the tlauncher don’t recognise the openJDK as a java. What should I do to make it work ? ( I am using windows)

Why are you using Tlauncher? Why aren’t you using the normal Minecraft launcher?

because most of us cant afford actual minecraft
