How to use "OR" in filterByFormula API field?

[TFP]

I’ve successfully applied both those conditions distinctly:

• filterByFormula: {customerOwnerRef} = ''
• filterByFormula: {customerOwnerRef} = '${process.env.NEXT_PUBLIC_CUSTOMER_REF}')

But I don’t understand how to make a logical OR between both conditions, I tried the following but it fails with INVALID_FILTER_BY_FORMULA error:

• filterByFormula: {customerOwnerRef} = '${process.env.NEXT_PUBLIC_CUSTOMER_REF}' OR({customerOwnerRef} = '')

Nevermind, I found the solution while writing the question.

filterByFormula: OR({customerOwnerRef} = '${process.env.NEXT_PUBLIC_CUSTOMER_REF}', {customerOwnerRef} = ''),
