Screen mirroring app for Samsung A-series? (opens in new tab)

Hi all, As you may know, the A-series devices do not come with Smart View for screen mirroring\. I tried to side-load it but that didn't work\. Has anyone been able to set up screen mirroring on their Samsung A-series? I have a Galaxy A14 5G for reference\. I am trying to screen mirror to a Roku, so Google Home/Chromecast WILL NOT work\. Thanks for any hints\!
