Bitwarden also does this, with a big modal popup - and I only use my password manager in the middle of a flow. I'm either in the middle of signing up for some thing to accomplish a goal (like checking out on a website), or logging in to something to do the same.

I'd much rather it prompt on app close (when I don't care how long the update will take), or just have a button in the UI that I can click at my leisure.
