it pushes with no error and i watched the tables in side the amplify studio it was perfect but i want to pull it to create the class models for me, for next use. cause without models there is nothing i could deal with

and this is my graphql code:

type Users @model @auth(rules: [{allow: public}]) {
  userId: ID!
  email: AWSEmail

  follow: [FollowClubs] @hasMany(indexName: "byClub_follow", fields: ["clubId"])
}

type FollowClubs @model @auth(rules: [{allow: public}]){

  topicId2: Topics @belongsTo(fields: ["topicId"])
}

type UserChats @model @auth(rules: [{allow: public}]){
userChatId: ID!
content: String
userIdSender: ID! @index(name: "byUser_userChatSender")
userIdReciever: ID! @index(name: "byUser_userChatReciever")
userIdSender2: Users @belongsTo(fields: ["userIdSender"])

}

type Rooms @model @auth(rules: [{allow: public}]){
  roomId: ID!
  name: String!
  description: String
  dateTime: AWSDateTime
  participants: [Participants] @hasMany(indexName: "byRoom_participants", fields: ["roomId"])
  founderId: ID! @index(name: "byUser_rooms")
  founderId2: Users @belongsTo(fields: ["founderId"])
}

type Participants @model @auth(rules: [{allow: public}]){
  participantsId: ID!
  role: String
  joinDate: AWSDateTime
  peeringId: ID! # this must be an auto generated id
  userId: ID! @index(name: "byUser_participants")
  roomId: ID! @index(name: "byRoom_participants")
  userId2: Users @belongsTo(fields: ["userId"])
  roomId2: Rooms @belongsTo(fields: ["roomId"])
  participantIdSender: [RoomChats] @hasMany(indexName: "byParticipants_participantIdSender", fields: ["participantsId"])
}


type RoomChats @model @auth(rules: [{allow: public}]){
  roomChatId: ID!
  content: String
  participantIdSender: ID! @index(name: "byParticipants_participantIdSender")
  participantIdSender2: Participants @belongsTo(fields: ["participantIdSender"])
}

A 'belongsTo' field should match to a corresponding 'hasMany' or 'hasOne' field
