Answer

If you click edit then you can see that certain words have been erased and replaced by question mark emojis

These can be replaced to complete the paragraph:

I can wave my hands at you, but I never say goodbye.
You are always cool when with me, even more so when I am high!
If you want to be in too, find missing sentence/word.
It is just simple riddle so… but now I have to go, bye…

The added letters can be joined to give

I wave to in fin it y

So the final answer is, you wave to

INFINITY

Also fits the hint of 'something beyond'
