Tabela que relaciona ID de produto e ID de marca - Java

Projeto CRUD

Product Model:

package com.example.springboot.models;

import jakarta.persistence.*;
import org.springframework.hateoas.RepresentationModel;

import java.io.Serial;
import java.io.Serializable;
import java.math.BigDecimal;
import java.util.UUID;

@Entity
@Table(name = "TB_PRODUCTS")
public class ProductModel extends RepresentationModel<ProductModel> implements Serializable {
    @Serial
    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private UUID idProduct;
    private String name;
    private BigDecimal value;
    @ManyToOne
    @JoinColumn(name = "brand_id", referencedColumnName = "idBrand")
    private BrandModel brand;

    public UUID getIdProduct() {
        return idProduct;
    }

    public void setIdProduct(UUID idProduct) {
        this.idProduct = idProduct;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public BigDecimal getValue() {
        return value;
    }

    public void setValue(BigDecimal value) {
        this.value = value;
    }

    public BrandModel getBrand() {
        return brand;
    }

    public void setBrand(BrandModel brand) {
        this.brand = brand;
    }
}

Brand Model:

import jakarta.persistence.*;

import java.io.Serial;
import java.io.Serializable;
import java.util.List;
import java.util.UUID;

@Entity
@Table(name = "TB_BRANDS")
public class BrandModel implements Serializable {
    @Serial
    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private UUID idBrand;
    private String name;
    @OneToMany(mappedBy = "brand", cascade = CascadeType.ALL, orphanRemoval = true)
    private List<ProductModel> products;
    public BrandModel() {
    }

    public BrandModel(String name) {
        this.name = name;
    }

    public UUID getIdBrand() {
        return idBrand;
    }

    public void setIdBrand(UUID idBrand) {
        this.idBrand = idBrand;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

Tudo está funcionando, apenas a tabela que relaciona id da marca e id do produto nao está cadastrando nada. Como posso resolver? Acredito q utilizei a anotacao @OneToMany ou @ManyToOne de forma errada.
