How do i use Itemsadder materials in menu | HelpChat | Page 1

I followed the documentation and have spent several hours trying to solve the issue, menu works. But the icon is blank in the menu

    material: 'itemsadder-magic_store:ms_mc_medieval_bed_01_acacia' 
    model_data: 10068
    slot: 1
    display_name: '&e&lAcacia Bed'
    lore:
    - '&7A rare bed' 
    - ''
    - '&7This item costs &a&l$1000'   
    left_click_commands:
    - '[takemoney] 1000'
    - '[console] iagive %player_name% magic_store:ms_mc_medieval_bed_01_acacia' 
    - '[sound] BLOCK_COMPARATOR_CLICK 1 5' ```
