I cant display points. I can't change the style points/polygons.

I have only polygons and points in my database. It is in one table and one column. I do not store any more signs (river, house, etc. ... this is not).
Polygons are displayed normally. I just need to display the points, with my own style. It's strange why the points are not shown.
Also, I cannot change the style for all polygons.
I looked at the help. Perhaps I need something much simpler ...
Thank you in advance!

<script type="text/javascript"  src="https://unpkg.com/leaflet.vectorgrid@1.2.0"></script>

<script>
var vectorTileStyling = {}
var openmaptilesUrl = "http://192.168.0.57:8080/{z}/{x}/{y}.pbf";
var openMapTilesLayer = L.vectorGrid.protobuf(openmaptilesUrl, {
	vectorTileLayerStyles: vectorTileStyling,
	attribution: '© OpenStreetMap contributors, © MapTiler'
});
...
var overlays = {
	"Vector Tiles": openMapTilesLayer
};
...
L.control.layers(baseLayers, overlays).addTo(mymap);
</script>

SQL on server:

WITH webmercator(envelope) AS (
  SELECT ST_TileEnvelope(15, 20891, 9773)
)
SELECT ST_AsMVT(tile) FROM (
	SELECT osm_id , tile1 FROM (
	  SELECT osm_id, ST_AsMVTGeom(poly3857, (SELECT envelope FROM webmercator)) as tile1
	  FROM polygon43
	) a
	where tile1 is not null)
AS tile

Start with the Leaflet.VectorGrid setup, especially the empty vectorTileStyling object and the vectorTileLayerStyles option, then inspect the supplied ST_AsMVT query for how point and polygon geometries are returned. Reproduce the map with the provided tile URL and SQL, and consider the issue complete when points render with a custom style and all polygons can be styled.
