How to get a string containing the word connect from an array with strings?

I have an array like this

const arr = [
  '_ga=GA1.1.399070869.1649559884',
  'origin=s%3ACYm5bKjhAM1mfanrjJ8bqR_CAHffLVzj.MImlJ0gl2DTN%2BwRPmE0ZbQqI3nHwSVDt70DNyEd2Luw',
  'user=Zina',
  'connect.sid=s%3AvNWJDoh08zdqHE1k8P53CoDmLqI87GDO.%2BLdCgtZ%2F5gv%2BjdK1z0FiUoehYauJHCgrz9T2tZYX%2FI4'
]

I will not think in any way how to receive an index terms where the line begins with “connect”.

get rid of suggestions like

arr[4]

since this line can be anywhere
