[sandbox] serviceProfile state

[API_User]

Hello !
In sandbox, how could i change the serviceProfile state ?
Because when i tried to add a connection on it ( POST /ecx/v3/l2/connections )
I have :

"Profile is not yet APPROVED"

Profile uuid : 52686861-0f6d-4b1e-bc69-56076a978c18
Best regards,
Louis
