I'm trying to remove the filter icon in ag-grid **whilst keeping the filtering box**

Right now I'm trying to use pure css to hide the icon which in webpack just adds the `aria-hidden="true"`

**CSS I've tried**

```
* /deep/ div.ag-floating-filter-button{
    display:none !important;   
}

```

**Trying to remove this icon**

I either want to completely remove the grid icon using `columnsAPI` or find a way with CSS to disable the icon truely.
