Since internationalization of previewers (as external tool) is now possible, at least for French, it probably would be useful to add
toolName in manifest json and to add in Bundle.properties a list for each toolName
externaltools.'toolName'.displayname
Some initial steps - planning to update the curl commands in the README to include a toolName and just added a Dataverse PR (#7478) to continue showing the default displayName until the toolNames get in the Bundle.
