Nextcloud App Development

I am looking for a developer to create a custom Nextcloud app that adds a button that generates an iframe embed code for any Nextcloud file.

The app should use all default Nextcloud systems such as the document viewing/permissions from Nextcloud Office, be functional for any Nextcloud install up to the latest v29, and use the built‑in Nextcloud Office viewer for the embedded item.

The app will be open sourced, published to the Nextcloud Hub and on Git Hub, and should add a “Generate Embed Code” button on the Nextcloud Share Dropdown to handle document embedding with sharable permissions.

• Development of a custom Nextcloud app with a button that generates iframe embed codes for Nextcloud files.
• Seamless integration within the Nextcloud environment with user‑friendly functionality.
• Use of the internal document viewer for the embedded view while addressing constraints such as CSP policy and frame origin.
• Skip the “Guest Name” popup modal so the embed shows only the document with viewer controls.
• Optionally integrate CSP editor functionality to bypass CSP restrictions (not required).

• Prefer the built‑in document viewer for the embedded view system.
• Address Nextcloud’s default CSP Policy/Frame Origin restrictions, potentially by incorporating CSP editor features.
• Eliminate the “Guest Name” popup modal so the embedded content displays only the document and viewer controls.
