Click Button in Internet Explorer using VBA

I've been round and round with this. I am absolutely fresh with VBA and have no clue what I am doing, so any help would be highly appreciated!

For now, I simply want to the click the button on a work website. The button is labeled as "ENTER (Click here to Login)"

I've tried several different options gathered from around the internet and back, but have had no luck.

My current setup:

Sub RoundedRectangle1_Click()
Dim IE As Object

'open up Internet Explorer
Set IE = CreateObject("InternetExplorer.Application")

IE.Visible = True

IE.Navigate "http://confidential.website"
    
'Wait for IE to load
    Do While IE.Busy

    Loop
    
'wait for site to fully load
Application.Wait Now + TimeValue("00:00:03")

'click link
IE.GetElementsByTagName("button").Click

End Sub

HTML text is attached!

Any recommendations?
Thank you in advance!
