Pulling image from private regisrty using cri-o

hi all,
i was learning kubernetes and i was facing an issue.my requirement was to deploy an image from private quay registry without mentioning imagepullsecrets in yaml file.i heard that we can do it using cri-o.where crio pulls the image from private web registry.so kindly help me,That how can use cri-o to pull images from web private quay registry

Something like this:

crictl pull --auths <my_auth_string> <image>

Afaik this uses auth-tokens which seem to be deprecated. The Quay.io Page has this statement:

NOTE: Access tokens are currently deprecated and should not be used. Robot Accounts are their replacement

I don’t know how to use/handle these and actually very little info about the robot-accounts can be found
