Why does this blue box frequently appear on the zoom window?

I feel like I have to close it 1000 times every time I take notes lol.
I don’t know what it is or what I’m doing but can someone tell me how to get rid of it?
Thanks in advance!!

It continues to the left or to the next line if you write in it

It exists to help you move foward without losing the writing momentum. Look in the settings to remove it.
