Create Minecraft Holograms 1.14?

I can create a hologram with a command, but I do not know how to write multiple lines (word-wrap).

Without Clientmod this is impossible to my knowledge…

How to make the other server? Simply spawn several lines with each other

To correct myself even further, you can add another line under a nametag by scoreboard. But in this line you can write only one number, so not so useful!
