Iterate through Object of arrays to display in a table

I have an object returned from an API call and I an trying to show the object details in a table in HTML. I am able to get the key but not getting the values. I am using angular 7.

I have tried let keys = Object.keys(successMsg.body.result); which gives me "ABC", how do I get the othet values?

In the HTML I am using :

<tbody> 
<tr *ngFor="let data of dataToShow | keyvalue"> 
<td> {{data.key}} </td> 
<td> {{data.value}} </td>
</tr> 
</tbody>

The api data is: { "ABC": [ "1234567" ], "XYZ": [ "5678912" ] }
