Bash- find- permission denied stuck?

I am trying to get files older than 3 days (by modified date, mtime) by find command (i want to exec rm command in future, doesnt matter why :D). Problem is I am not root user and there are mix of the files, of course. It looks, like simple script as hell gonna to stuck when occurs first permission denied message.

#!/bin/sh
find /tmp* -type f -mtime +3 -group jenkins -print
# -exec rm {} \;

Output is just error message (owned by root user) find: ‘/tmp/systemd-private-dbe33161924b4616a037608d052f48d0-httpd.service-sFr4Wd’: Permission denied

Notice- there are many files which should occur in find command:

    ll /tmp | less
    ....

...

I have tried to avoid permission denied message following:

 1. 2>/dev/null OR 2>&- (add on the end, error output to null redirect)
 2. find -type d ! -readable -prune -o ...  (exclude not readable folders)
 3. find /tmp* -type f -mtime +3 -group jenkins -print 2>&1 | grep -v "Permission denied" (should be same as above)
 4. find -user jenkins, as well as -user $(whoami)
 5. -perm -u+rwx

When I try to redirect error output to /dev/null, command output is blank

Kindly please,

Thanks

Oh, problem was probably in logic finding files, I have made two commands (find directories and files separately)

#!/bin/sh
find /tmp -user $(whoami) -type d -mtime +3 -exec rm -rf {} \;
find /tmp -user $(whoami) -type f -mtime +3 -exec rm -f {} \;

And It looks like it works well, permission denied message still occurs, but commands are working.
