Getting from Property Statement link to Property Label with Sqarql/wikidata

first time poster here, because i am desperate.

in a Sparql query i have a result column, where pLabel is not accualy the property, but the ps:/pq: type. i would like to get the label of the property (ex. ps:P61-> "winner"). how do i achieve that?

SELECT DISTINCT ?topstatement ?topstatementLabel ?target ?targetLabel ?p ?pLabel ?pointInTime {
  VALUES (?target) {(wd:Q937)}
    ?statement (
              pq:P571
              |pq:P575
              |pq:P585
             ) ?pointInTime .
  ?topstatement ?wdq ?statement .
  ?statement ?p ?target .
  
  SERVICE wikibase:label {bd:serviceParam wikibase:language 'en'}

}

on wikdiata query service

i tried by myself on wikidata query service and after hours i even tried ai which could not help me eighter

Property labels in Wikidata are linked to the property entities. In the case if qualifier, the property entity is linked to the property with wikibase:qualifier, so you'll get it this way

SELECT DISTINCT ?topstatement ?topstatementLabel ?target ?targetLabel ?p ?pLabel ?pointInTime {
  VALUES (?target) {(wd:Q937)}
    ?statement (
              pq:P571|pq:P575|pq:P585
             ) ?pointInTime .
  ?topstatement ?wdq ?statement .
  ?statement ?p ?target .
  
  ?qualifierEntity wikibase:qualifier ?p;
                   rdfs:label ?pLabel.
  FILTER(LANG(?pLabel)="en")
  SERVICE wikibase:label {bd:serviceParam wikibase:language 'en'}

}

For direct properties, you should use wikibase:directClaim
