Can't access packages for group

I read here:

that the pattern required to acces my pipy package repository is the following:<group_id>/-/packages/pypi

If in gitlab I go visit my group’s package repository I can see the package has been published there.
If I try to access the pypi url all I get is 404. I tried it from also from Postman using basic http auth and I filled in my deploy token details but still, all I get is 404

Can anyone help ?
