How to use html elements for custom text in promts?

PUT https://TENANAT/api/v2/prompts/login/custom-text/en
Authorization: Bearer XXX
Content-Type: application/json

{ “login”: { “description”: “

test ${companyName} /n to continue to ${clientName}.
” } }

I’m getting error
{
“statusCode”: 400,
“error”: “Bad Request”,
“message”: “Key "description" in screen "login" has invalid characters.”,
“errorCode”: “invalid_body”
}
