How to style Mapbox’ Heatmap

I have this GeoJSON (can be downloaded here). The data is distributed through a grid, thus the points are distributed regularly.

How to programmatically trigger a click on a marker on a map?

There is such a demo in the Mapbox documentation https://docs.mapbox.com/mapbox-gl-js/example/cluster/. Here they set an event listener for a specific layer map.on('click', 'places', (e) => {}). But what if I want to call it programmatically, for example, when loading a page, show a popup for a specific placemark on the map?

At a specific zoom level, the transparency of the features in the Mapbox GL JS map will become 100%, instead of the 50% transparency I set

mapbox-gl-js3.2.0 + Vue2.6.11
When the map is scaled to level 11, the transparency of the vector graphics will not be the same as the transparency I set, but will become 100%. The three parameters output by the console are map. getZoom(), map. getPaintProperty (‘mvtBase ‘,’ fill space ‘), and map. getPaintProperty (‘mvtBase’, ‘fill color’)
