Forgot to add salt …

Hi folks

My third attempt at sourdough. First was a fail, second came out great although a bit dark on the top, third has been shaped and is in the fridge and I’m just realizing I didn’t add salt to the dough at all.

Will this bread be terrible without salt? If there a way to get some salt in to an already shaped and cold proofing dough?!?

Here’s the recipe I am using if that matters: https://www.farmhouseonboone.com/beginners-sourdough-bread-recipe/
