Add Content-Type to Code Generation

The Code Generation shows me

curl --request POST \
  --url https://api.database.cric.com.br/api/v2/usuarios/login \
  --data '{"email":"string","senha":"string"}'

but the server that I wrote is expecting the user to provide Content-Type:

curl --request POST \
  --url https://api.database.cric.com.br/api/v2/usuarios/login \
  -H "Content-Type: application/json" \
  --data '{"email":"string","senha":"string"}'

How can I customise the Code Generation to include the Content-Type?
