This is how I manage enemy's collision with tilemap

[Leito4G]

Here’s my code in case it helps anyone

public class EnemyMovement : MonoBehaviour
{
[SerializeField] private float moveSpeed = 2f;
[SerializeField] private Vector2 direction;

private Rigidbody2D rb;
private RaycastHit2D raycastHit;
private LayerMask groundLayer;
private void Awake()
{
    rb = GetComponent<Rigidbody2D>();
}

private void Start()
{
    groundLayer = LayerMask.GetMask("Ground");
    direction = Vector2.right;

}

private void Update()
{
    rb.velocity = direction * moveSpeed;

    raycastHit = Physics2D.Raycast(transform.position, direction, .5f, groundLayer);
    Debug.DrawRay(transform.position, direction * .5f, Color.red);
    if(raycastHit.collider != null)
    {
        ChangeDirection(-direction);
        FlipEnemy();
    }
}

private void ChangeDirection(Vector2 newDirection)
{
    direction = newDirection;
}

private void FlipEnemy()
{
    transform.localScale = new Vector2(direction.x, transform.localScale.y);
}

}
