Customizing asset card view 'hover' actions - where are they located please?

We have a client that wants to customize the actions on the assets card view page, the ones displayed when you hover over an asset card (e.g. Edit, Select, etc.). How can this be done? I'm able to customize the actions on the asset details page (defined in dam/gui/content/assetdetails/jcr:content/actions), but I'm not able to find those on the assets card view page.

Is someone able to help us locate these, please?

Thanks.

Mike
