Add Individuals to owl file with SPARQL query

Question

i want to insert some individuals into my ontology owl file (OWL/XML) with SPARQL using Protege for example :

person1 is an instance of class person and has these object property assertions : hasname Alex, hasage 26

Here is my code

PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX owl: <http://www.w3.org/2002/07/owl#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
PREFIX my_onto: <http://www.semanticweb.org/hp/ontologies/2020/5/personOnto.owl#>
    
INSERT DATA
{
   my_onto:person1 rdf:type my_onto:person .
               rdf:type owl:NamedIndividual .
                my_onto:hasname Alex.
                my_onto:hasage 26.

}

But, i had this error :

Caused by: org.openrdf.query.parser.sparql.ast.ParseException: Encountered " "insert" "INSERT "" at line 7, column 1.
Was expecting one of:
