Only Substance Surface is not visible when loading sbsar in Maya Hypershade

Currently, I set the project folder in Maya and then create with Adobe Substance > set the save destination to the Substance folder of the Maya project. Load sbsar with Substance node in Maya > Set Workflows to Arnold > Click Create Network, but only Substance Surface is not displayed. stomach. Do you not understand the Adobe Substance 3D Painter and Maya project folder settings?
