Solar lens needed for Nikon Coolpix P900

[TNphotogirl]

I'm not a professional and really don't know a LOT about lens and such. I've been Googling lens but it shows me either regular lens, macro lens, etc. Anyone know/recommend a solar lens I need for my camera for the solar eclipse next month? I don't want to spend a lot so am looking for something cheap but won't ruin my camera or my eyes

This and rubber band is all you need. Pull it tight to keep the film flat. Or this if you want smaller.
