Correction to: Nature Cell Biology, published online 23 June 2022.

In the version of this article initially published, in the bottom (fMLF + GW4869) row of Fig. 2c, the second (Ld) and third (RBG) images were reversed. The figure has now been corrected so that the red Ld image appears second and the yellow/blue RBG image appears third in the HTML and PDF versions of the article.
