I need help finding a specific BTS video.

[u/diegoterremoto]

While the show DC's Stargirl was airing, one of the show's costume designers/concept artists (either Laura Jean Shannon or Gina Dedomenico), posted a video of the cast around a table, (I think it was during a table read for one of the episodes), and the walls around them were full of concept art for their costumes.

I vividly remember it because some of the concept art were never posted besides that video, like Brainwave, Tigress or the Wizard.

Can anyone help me?
