Is there a way to create a prompt screen for a user to select a file

So, im trying to put together a code that would convert a file from a pdf to a word. i figured out the word issue, thanks to help from the forum. My next question is it possible to create a prompt screen, that would direct a user to have to select a file to be converted?

Yes, this will do that for selecting a PDF:

Add-Type -AssemblyName System.Windows.Forms
$FileBrowser = New-Object System.Windows.Forms.OpenFileDialog -Property @{
 Multiselect = $false # Multiple files can't be chosen
 Filter = 'PDF Files (*.pdf)} | *.pdf' 
If($FileBrowser.CheckFileExists = $true) {
 $FileBrowser.FileName #Lists selected file. Do whatever here instead.
