Using Regex to define search pattern for Spacy rule

Question

I have a spacy model and want to include some manual changes to that with the following code

patern = "Juden.*"

#Ruler to correct problems
patterns = [
    {"label": "MISC", "pattern": "erwartete"},
    {"label": "MISC", "pattern": "Jahren"},
    {"label": "MISC", "pattern": "entwöhnte"},
    {"label": "MISC", "pattern": "Juden"},
    {"label": "MISC", "pattern": {patern}}

]

ruler = nlp.add_pipe("entity_ruler", before ="ner")
nlp.analyze_pipes()

ruler.add_patterns(patterns)

everything works well, but I want to combine the regex module with spacy so that I can extract ALL words which start with Juden , followed by any character.

e.g. Judenthum, Judenhass, Judennot, etc.

I tried to set up a variable patern with the regex expression which works itself, but I am now struggling to include this into my patterns of the spacy model

Any suggestions or advices?

Thank you !
