Why should I ‘refresh’ Direct Lake models in Microsoft Fabric?

Unfortunately, the provided content is incomplete. The only available content seems to explain that there is a new mode called Direct Lake in Microsoft Fabric that combines the advantages of Import mode and Direct Query mode and that it directly accesses files without requiring extra steps. However, the content abruptly ends with "This means..." and there is no further information provided. The title suggests that the author might have discussed the importance of refreshing Direct Lake models but without the rest of the content, it cannot be confirmed.
