[SalesForce] Owner name is not getting populated in LWC by using @wire decorator

I've created LWC to populate opportunity fields in read-only mode. able to display all fields except opportunity owner. I've gone through multiple solutions provided by salesforce experts & done multiple changes in the js file, still facing the same issue.

.html file:

<template>
<lightning-card>
    <!-- Opportunity -->
      <!-- Display -->
        <template if:true={existingOpportunity}>
            <lightning-record-edit-form 
            record-id={existingOpportunity}
            object-api-name={opportunityObject}
            >

Can anyone please suggest what exactly i'm doing wrong in code. I've tried with putting recordid value in js file still no luck.

I want to display owner name in text format, currently it is showing in hyperlink to user record.
