use real people, this is what i do
make sure the GMB is complete and get the Share url
using your Facebook, Whatsapp or LinkedIn contact and reach each one of your contacts and ask each one if they can leave you a review, in my case i always provide the text and link
do that and you will see that those reviews will stick and easily, you could get 100 to 200 reviews in a week
in my case works and its free
