Do you want to add indexes for this tool form option? built-in pharokka DB
When wrapping the tool, did you also create a Data Manager to create/add indexes (by an admin)? If not, then try contacting who was helping you before (private), or the EU admins at their Lobby chat here (public) https://matrix.to/#/#usegalaxy.eu:matrix.org. Indexes can be server specific, and not all involve a DM, but that is how to start.
