You'd probably want to use a strip of "cavity closer" bottom and sides

You don't need a lintel when the blocks will support the triangle of
brickwork above. Nor do you need a cavity closer, just complete the wall
& insulation the same way as the rest of it.

Just checking - are you saying that the lintel should be removed?

I assume that there is one if this is a window opening.

I'm saying there's no need to add one. That should be fairly obvious, but Andy's comment was interpretable that way.
