PS + games playable forever (JC4)?

On the playstation you can now (if you have ps +) download Just Cause 4 until December 23rd, 2020. You can, of course, play it, but do you keep it forever, so can you still play it after December 23rd or is it only playable for a limited time?

Can only play as long as you have PS Plus

It is playable as long as you have PS Plus. D.H. If your PS Plus expires, you will no longer be able to play it. But when you buy it again, it works again.
