InterSystems AllergyIntolerance FHIR resource DTL shows Severity value as SV and Category Food Allergy as FA

Hi Community

I am using a standard DTL for Allergy Intolerance but it shows codes for Category and Severity Columns on cliinical viewer.

I have copied the standard DTL to my custom folder and I want to modify it to show descriptions for these two columns but I don't know how to do it.

Please see the below DTLs for Category and severity and advise how I can change them to get descriptions.

Category DTL section

<if condition='source.category&apos;=""'>
<true>
<if condition='source.category.Count()>0'>
<true>
<assign value='##class(HS.FHIR.DTL.Util.Lookup).Code("vR4","SDA3","allergy-intolerance-category|4.0.1","HS.SDA3.CodeTableDetail.AllergyCategory",source.category.GetAt(1))' property='value' action='set' />
<if condition='value&apos;=""'>
<true>
<assign value='value' property='target.AllergyCategory.Code' action='set' >
<annotation>
<![CDATA[ The external code, e.g. "M"
 --- This mapping entry seeks a lookup table entry that can match a source value with a target value for this field. If the mapping cannot find the lookup table, or cannot find a matching entry in the lookup table, and it has a non-empty Default Value defined, it places its Default Value into the target field. Otherwise, the target receive no value from this mapping.
 --- FHIR4 AllergyIntolerance:category is a *List*, and SDA3 HS.SDA3.Allergy:AllergyCategory.Code is *Single*.
 --- For a list of objects mapped to a single object, when the transformation is FHIR to SDA, the transformation maps the first object from the source list to the target, and discards the others. ]]>
