Is there any solution to delete thread mails

Question

Is there any solution to delete thread emails. My solution deletes based on id and it takes time.

import imaplib
import email
from email.header import decode_header
user= "xxxxxxx"
app_password= "xxxxxxxxxx"
host = 'imap.gmail.com'

imap = imaplib.IMAP4_SSL("imap.gmail.com")
imap.login(user, app_password)
imap.select("INBOX")

status, messages = imap.search(None, 'SUBJECT "Appvila: Developer Test"')
messages = messages[0].split(b' ')
print(messages)
print(len(messages))
for mail in messages:
    _, msg = imap.fetch(mail, "(RFC822)")
    for response in msg:
        if isinstance(response, tuple):
            msg = email.message_from_bytes(response[1])
            subject = decode_header(msg["Subject"])[0][0]
            if isinstance(subject, bytes):
                subject = subject.decode()
            print("Deleting", subject)
    imap.store(mail, "+FLAGS", "\\Deleted")
imap.expunge()
imap.close()
imap.logout() 

I have thread mails but my solution takes one by one id and deletes is there any solution to delete completely
