Get column value, not ID, from a look up column

Question

thank you for reading; my problem is:

I want to retrieve the values of the column "GroupWithPriority". That column is a Look Up from other list.

When I try to get the value, all I get is "GroupWithPriorityId" that gives only a number when I want to get the text... is it possible to do what I want?

I want to get "Group 1" but instead I get

I have already reached a lot and I found nothing :c

I would appreciate your response even if that means that there is no way to do what I want, thank you

My retrievement code looks something like this:

this.context.spHttpClient.get(requestUrl, SPHttpClient.configurations.v1)  
            .then((response: SPHttpClientResponse) => {  
                if (response.ok) {  
                    response.json().then((responseJSON) => {  
                        if (responseJSON!=null && responseJSON.value!=null){  
                            console.log(responseJSON.value);    
                        }  
                    }); 
                }  
            });

In order to access values from the lookup column from a REST query, you need to add the $expand parameter to your REST URI to specify the name of the column to expand, then reference the fields in your $select prefixed with the Lookup columns name, the / character and the name of the field from the reference lookup item you wish to select. For example:

/_api/web/lists(guid'<guid>')/items?$select=Title,ID,LookupField/FieldInTargetList&$expand=LookupField
