Minecraft: Java: 1.14.2: / give @p [level = 30] example 01?

I would like to use this command tinker an XP shop. My problem is that you have to have exactly these levels of levels. Is there a way to insert a minimum? That all players with more levels can still buy this item?

Thank you for answers!

(Smaller Edit: In previous versions, this works with [lm = 3]. Does anyone know what this looks like in the latest version?)

That should be like this:

@p [level = 30th]

Exactly us at distance or score or something, n'e?

I use this with all my teleport CommandBlocks. But that works at level too… I was just too stupid for that.

You're welcome!
