Hello,
With this question, I would like to suggest you first check the
QuickStart:Receiving shared content sample. To received which data format, each Target App has its own ShareTarget contract defined in the its app's manifest.
If you want your app to receive shared content as a target app, you need to first configure your app's manifest file to indicate that it supports the Share
Target contract. This contract lets Windows present your app as an option when the user invokes the Share charm in scenarios where supported data formats are shared. When choosing data formats for your target app to support, you should only register for only
the formats that your app can handle. For more guidance, please see Choosing data formats. When the user invokes the Share charm, Windows automatically shows
only the target apps that support the data being shared.
more details please refer the following article: Sharing and receiving content (Windows Store apps using JavaScript and HTML)

Hope this helps, thanks.
