How to open a form in VB.NET even with the main form minimized

Good morning, good afternoon, good evening, person! I'm having the following difficulty:

I put it to an open form when it reaches the 30 and 60 second mark. All right, that worked, but only when I'm with the main form open (not minimized), but I need it to open, even with the main form minimized, how can I do that?

My code:

Public Class Form1
    Private Sub btnIniciar_Click(sender As Object, e As EventArgs) Handles btnIniciar.Click
        trmConometro.Start()

        If lblSegundo.Text = "02" Then
            MsgBox("Creeps saindo da base")
        End If
    End Sub

    Private Sub trmConometro_Tick(sender As Object, e As EventArgs) Handles trmConometro.Tick

        lblSegundo.Text += 1
        If lblSegundo.Text = "60" Then
            lblMinuto.Text += 1
            lblSegundo.Text = "00"
        ElseIf lblMinuto.Text = "60" Then
            lblHora.Text += 1
            lblMinuto.Text = "00"
        End If

        If lblSegundo.Text = "30" Then
            Creeps_saindo_da_base.ShowDialog()
        ElseIf lblSegundo.Text = "59" Then
            Creeps_saindo_da_base.Show()
        End If
    End Sub

    Private Sub Form1_KeyDown(sender As Object, e As KeyEventArgs) Handles MyBase.KeyDown
        If e.KeyCode = Keys.M Then
            trmConometro.Start()
        End If
    End Sub

    Private Sub btnParar_Click(sender As Object, e As EventArgs) Handles btnParar.Click
        trmConometro.Stop()
        lblSegundo.Text = "00"
        lblMinuto.Text = "00"
        lblHora.Text = "00"
    End Sub
    Private Sub trmSairMSG_Tick(sender As Object, e As EventArgs) Handles trmSairMSG.Tick

    End Sub
End Class

Thank you
