Facebook Catalog - Rich text product Descriptions sincro error

Hi, I’m having trouble synchronizing my Facebook catalog due to an error with my rich-text product descriptions.

In Shopify, my descriptions are rich text (HTML) and Facebook requires me to send rich text descriptions in a different field. But I don’t know how to personalize this since the sincro between my Shopify products and my Facebook catalog is made automatically.

Does anyone have experience on how to solve this? How should I tackle my Shopify store configuration for it to be optimized for Facebook/Instagram shops?
