I want to create sub admin role with own customer access permission. That means sub admin will login in admin panel and able to create sustomers. Sub admin can see only own customers, nothing else.
Please let me know how can I do this in Magento 2. Thanks
You won' tbe able to do without customization or maybe a 3rd-party module.
This feature is similar to the multitenant/acl rules per website feature you can find at Magento Commerce, but is not restricted per "sub admin".
The restriction is per website in that case.
Maybe you can explore the marketplace: https://marketplace.magento.com/catalogsearch/result/?q=acl#q=permission&idx=m2_cloud_prod_default_p...
