Here I've uploaded a file to storage. Now how can I change a cell/create record of some table by adding it to a record? (RestAPI)

Unfortunately, in my client for Http requests (Ktor) I can't pass anything other than String.

To summarize: I need to make a POST with this FormData

{
  "number": "123123",
  "close time": "string",
  "close location": "string",
  "open time": "string",
  "open location": "string",
  "attachments": [{"url":"https://nocohub-001-prod-app-attachments.s3.us-east-2.amazonaws.com/nc/uploads/2023/10/21/08bca39258b20ad3e4300f2a76169d3fb02c5249/HPM8jgzGzuJqLDDbbk.png","title":"ktor_logo.png","mimetype":"image/jpeg","size":30207,"signedUrl":"https://nocohub-001-prod-app-attachments.s3.us-east-2.amazonaws.com/nc/uploads/2023/10/21/08bca39258b20ad3e4300f2a76169d3fb02c5249/HPM8jgzGzuJqLDDbbk.png?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Content-Sha256=UNSIGNED-PAYLOAD&X-Amz-Credential=AKIATUJCOBWTKOMQ5JMU%2F20231021%2Fus-east-2%2Fs3%2Faws4_request&X-Amz-Date=20231021T104627Z&X-Amz-Expires=7413&X-Amz-Signature=f11c2918fd2e2c49caab3d405f794650dbad75dd5abcb52476bda3afdc56c96f&X-Amz-SignedHeaders=host&x-id=GetObject"}]
}

But I can't do that because attachments is an array.
I with ktor can only pass strings.
