@Carlos93 After downloading in Chrome, slide down from the top of the screen and look for a notification that the file was downloaded. Click that notification and select open. If it is an apk (application) file, it will ask you if you want to install it.
"Eventhough I can get it from the actual Google Play Store or Samsung store?"
If you download and install directly from the Play store or Samsung's Galaxy Store, those should be compatible.
You said you were downloading using Chrome. When you download from sources outside the 2 stores you never know what you are getting.
