Entity Permission in Dynamics 365 portals

Hi,

I Have 2 user in Dynamics 365 Portals.

In Dynamics CRM Portals, I have 2 Entity List for 2 custom entity - 1. Custom Entity 1 and 2. Custom Entity 2.

According to my requirement,

User 1 can only see Custom entity 1 and user 2 can only see Custom entity 2 on Dynamics 365 Portals.

Both user can not see entity list of each other.

Please suggest me any proper solution.

Thanks!
