You can add filters while Embedding dashboard items.

While adding the embed script you can define a filter array that can have multiple filter objects. For variable naming and filter object structure, please check the following code.

<script>
  // if the id of the dashboard item is "67de24jh033889e", the variable name 
  should be "draxlrFilters67de24jh033889e". Dashboard item id can be 
  obtained from the Draxlr embed code

  const dashboard<dashboard-id> = {
		configuration: {
			hideLastUpdated: true,
    },
    filters: [
			{
				table: "applicants",
				field: "id",
				operator: ">", 
				value: "40000",
				// elementType : 'integer' | 'string' | 'datetime' | 'time' | 'boolean', (required for arrays)
	      // timeInterval: 'days' | 'weeks' | 'months' | 'years' (required with before_relative and after_relative)
			},
			..
		],
	}
</script>
