Additional development to PowerApp group management app

We are seeking an experienced Microsoft PowerApp developer to enhance a PowerApp group management application, originally designed to manage Microsoft 365 and security group memberships (refer to: https://github.com/einfachKim/mygroups). Core feature work we're looking for: • Add sorting so every results gallery can flip between alphabetical ascending and descending. • Surface richer details in the galleries and detail screens: group owners, group descriptions and the total number of members. • Provide quick-access views that let the user toggle between ❶ groups they own, ❷ every group they can see (irrespective of ownership) and ❸ groups where they are merely members. • Visually distinguish Microsoft 365 Groups from Security Groups with an icon or badge. Tech context The app is a canvas app that relies on standard Microsoft Graph connectors and the AzureADPreview connector. No data sources change; we are only extending the UI and the logic that builds the collections. Deliverables • Updated .msapp file with the above features fully wired. • Demonstration / Walkthrough proving the new views, sorting toggle and icon differentiation all work under a standard tenant account. Please review the requirements and the mygroups-manageusers PowerApps https://github.com/einfachKim/mygroups before submitting your proposal.
