How to use latex?

I’m creating a database with questions that use complex math equations. For that I need to use Latex.
I need to include in “Script/meta tags in header”:

But it doesn’t work in Bubble, it’s supposed to work.
The interesting thing is that I saw it work for the first time, then when updating it stops working.
Someone can help me?
Thank you.
