I'm going to take extra care not to clear away that notification on my computer.
Why don't you want to clear away the notification?
I'm planning to leave it there. I might need it and I don't want to delete it.
You should use social media in a way that works for you. If you want to leave notifications instead of clearing them away, that is a perfectly reasonable choice.
I'm going to leave it there for many days.
You do whatever you need to do to make the site easier for yourself. It's not harming anyone what you do with your notifications.
