Raven Dust to CRO

Got a question that hopefully someone can answer?? I purchased Raven this morning on Crypto.com and it’s asking if I want to convert crypto dust to CRO. What does that mean! I know Dust are basically small amounts of crypto but if I agree to this, will it move ALL of my Raven to CRO or just a very small amount? Sorry, Noob here to Dust topics. Thank you.
