Error in wordpress multiste with addon library

Hello thanks for your great plugin.

I have wordpress multi site.first when i add to post for example imported audio player the play button that called from svg file doesn’t load.

and I got error for this path:
wp-content/uploads/sites/12/ac_assets/uc_double_image_audio_player/controls.svg

and second isn’t it better that just add setting that import file in admin network panel, and other client doesn’t have to import packages file, and use the packages that network admin import for theme.

best regard
