Add a new row above the hunger bar?

[Squarebuilder]

Good day,

I wanted to ask if anyone knows of a way with Minecraft Script to expand the hotbar by one row above the hunger bar?
I've enclosed a screenshot of how I imagine it to be. The second screenshot is what it looks like on another non-modded server. That means it has to be possible somehow, but I don't know if it is possible with script.
I look forward to answers.

Kind regards

This is roughly how I imagine it:

nope this is not possible if you are using a plugin, all tho you can do it using a textures and mods, cuz mods EDIT minecraft and plugins ADD to minecraft so there is a huge diffrent between them, the closest you can get with no mods is texturepack or action bar.

Try using action bar and textures.
