Only pos.home.tile.render working, all other targets not working

We have added all the targets to check how they are working. But only able to view the home tile. How to view other targets. Not getting how to add to product and customer details pages.

after adding the extensions from https://admin.shopify.com/store/YOUR_STORE/apps/point-of-sale-channel/settings/pos-ui-extensions, pos.product-details.block.render is working. But, pos.product-details.action.menu-item.render is not visible.
