Show only assigned issue for user

hi all
in issue I would like to limit result to only “assigned to” for specific user.
when user Tom logged in erpnext, will show only your assigned issues.

i have try various combinations of “role permission manager”.
if i check “if owner” results is empty
if i check nothing results is a full list of all issue.

you have a solution?
thank you

i have used this

publish new owner field to doctype, linked to users

in mail alert i enabled
Issue -> Value Change -> Owner
for mail to owner

in role permission checked “if owner”

it works
Thank you
