create otc position OPTIONS

Hi dears, i'm trying to open a trade on DAX Option, but i can't do it.
if i tried to open otc position with ordertype "market" i received that response: "errorCode": "error.trading.otc.market-orders.not-supported-for-epic".
if i tried to open otc position with ordertype "quote" i received thas respose: "errorCode": "validation.not-null-conditional-set-value.request".
I read in reference that if i specify ordertype "quote" i must to set quoteId end level, so where can i read quoteId by a specific epic instruments?
Someone of you can trade options? Can you write an example?
thanks so much to everybody
