How to set the display mode to 'collapse' and hide labels by default?

[Jasonzzzzzzzzzzzzzz]

Hi there, I try to set the display mode to 'collapse' and hide labels in my config.json, but it doesnt work.

{
      "type": "FeatureTrack",
      "trackId": "bone-marrow_18_dense",
      "name": "bone-marrow_18_dense",
      "assemblyNames": ["Sheep_V2.0"],
      "category": ["Annotation"],
      "adapter": {
        "type": "BedAdapter",
        "bedLocation": {
          "uri": "https://file.kiz.ac.cn/sheepgtex/jbrowse2/chromatin_state/bone-marrow_18_dense.bed",
          "locationType": "UriLocation"
        }
      },
      "displays": [
        {
          "type": "LinearBasicDisplay",
          "displayId": "SetRGBColor_filt03",
          "trackDisplayMode": "collapse",     // set to collapse
          "trackShowLabels": false,              //hide labels
          "renderer": {
            "type": "SvgFeatureRenderer",
            "color1": "jexl:'rgb('+get(feature, 'field8')+')'",
          }
        }
      ]
    }

I want to make these two options the default:

the settings are actually on the 'renderer' (full config docs https://jbrowse.org/jb2/docs/config/svgfeaturerenderer/)

here is a sample config that does it

{
      "type": "FeatureTrack",
      "trackId": "gff3tabix_genes",
      "assemblyNames": ["volvox"],
      "name": "GFF3Tabix genes",
      "adapter": {
        "type": "Gff3TabixAdapter",
        "gffGzLocation": {
          "uri": "volvox.sort.gff3.gz"
        },
        "index": {
          "location": {
            "uri": "volvox.sort.gff3.gz.tbi"
          }
        }
      },
      "displays": [
        {
          "type": "LinearBasicDisplay",
          "displayId": "gff3tabix_genes-LinearVariantDisplay",
          "renderer": {
            "type": "SvgFeatureRenderer",
            "displayMode": "collapse",
            "showLabels": false
          }
        }
      ]
    }
