Registering IDbCommand and autowiring and testing

i've registered the following

builder.Services.AddScoped<IDbConnection>(
    _ => new NpgsqlConnection(builder.Configuration.GetConnectionString("DefaultConnection"))
);
builder.Services.AddScoped<RegionRepository>();

builder.Services.AddScoped<IDbConnection>(
    _ => new NpgsqlConnection(builder.Configuration.GetConnectionString("DefaultConnection"))
);
builder.Services.AddScoped<RegionRepository>();

i now want to change that in my CustomWebApplicationFactory like..

            var conn = services.FirstOrDefault(descriptor => descriptor.ServiceType == typeof(IDbConnection));
            if (conn is null)
            {
                throw new Exception("NpgsqlConnection is not registered.");
            }
            services.Remove(conn);
            services.AddScoped<IDbConnection>(
                _ => new NpgsqlConnection(_postgreSqlContainer.GetConnectionString())
            );

            var conn = services.FirstOrDefault(descriptor => descriptor.ServiceType == typeof(IDbConnection));
            if (conn is null)
            {
                throw new Exception("NpgsqlConnection is not registered.");
            }
            services.Remove(conn);
            services.AddScoped<IDbConnection>(
                _ => new NpgsqlConnection(_postgreSqlContainer.GetConnectionString())
            );

but doing this the 'regions' table cannot be found, i'd presume it's not registering it correctly. When not swapping the implementation, it finds my local db with my local appsettings connection string the table does exist because i'm also registering AppDbContext with entity framework(and those tests are passing, i'm currently converting everything to repositories)

Can someone point me in the right direction to write the following class so only the Command..

is accessible publically

public record UpsertAreaShapesCommand(
    long AreaId,
    List<Shapes>[] shapes
) : IRequest<Result<bool>>;

public record Shapes(
    string Title,
    Point[] Polygon
);

public record Point(
    double X,
    double Y
);

public record UpsertAreaShapesCommand(
    long AreaId,
    List<Shapes>[] shapes
) : IRequest<Result<bool>>;

public record Shapes(
    string Title,
    Point[] Polygon
);

public record Point(
    double X,
    double Y
);

what is the 'correct' way of writing this so Point and Shape are only accessible from that command
