How do i control visibility Form1 from Form2

I want to make Form1.Visable=true and Form2.Visable=false FROM Form2

What i have tried:

Form1 FRM1 = New Form1;
FRM1.Show();

What I want: I want to make form1 visible = true from form2 code without creating a new form1

I can do it with VB.NET but i can't do it with C#

Pass a reference of the form you want to close to the form you want to be able to close it from.

Explicitly passing reference:

public class Form1
{
    public Form1()
    {
        new Form2(this).Show();
    }
}

public class Form2
{
    Form1 form1;
    
    public Form2(Form1 form1)
    {
        this.form1 = form1;
        form1.Hide();
    }
}

Passing the reference by setting Form2's owner:

public class Form1
{
    public Form1()
    {
        new Form2().Show(this); // show Form2 with Form1 as it's owner
    }
}

public class Form2
{
    public Form2()
    {
        this.Owner.Hide(); // hide this form's owner, in this case Form1
    }
}
