About Order Type STOP_LOSS

Hello, this is my first post, i’m curious about the api documentation about Spot Trading, you can see that STOP_LOSS apparently is available but there isn’t any spot trading pair with this option. Maybe i have to enable some option in my api key?

STOP_LOSS is not enabled. You may find all available order types of each symbol from the endpoint
/api/v3/exchangeInfo

What reason for disabling Stop orders for all assets? Is this temporary problem, or STOP_LOSS never had approved, really declared but absent?..
