Data driven approach on Attachments - power portal

[VVDynamics]

Hi Experts, I am quite new to power portals. I am trying to retrieve attachments from dataverse using fetchxml through webtemplate, where in if I add filter condition for request.params.id the results are always 0.  I am guessing the ID being passed might not be the one I am checking, but unsure how to pass ID from advance form step to basic insert form (attachments being displayed in subgrid)

<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false">
<entity name="caaci_genericformsubmissionattachment">
<attribute name="caaci_genericformsubmissionattachmentid" />
<attribute name="caaci_name" />
<order attribute="caaci_name" descending="false" />
<filter type="and">
<condition attribute="caaci_genericformheaderid" operator="eq" uiname="ENL1234 - Apply for Initial ENL Application Licence" uitype="caaci_genericformheader" value="{7999E32A-0364-ED11-9561-0022481B58DE}" />
</filter>
</entity>
</fetch>

it gives 5 results from dataverse, if I place value="{{request.params['id']}}" results are 0.

Update:

Even though there is an ID in the request.params, the filter is still giving 0 results.  I have tried other posts here where suggesting to place filter and attributes in order, nothing worked for me 😞
