How do I export math equations written in LibreOffice to InDesign?

I need to format a book in InDesign. The writers have written all the text in LibreOffice. There are many high-level equations placed throughout the text. I’m trying to figure out if there is a way to get the equations into inDesign. I’ve researched MathMagic and MathType but I’m not clear on the conversion process.

Thanks in advance for any advice.
