[GSTJ]

Note: erase all explanatory text from this template, replacing it with your words/images.

📝 DESCRIPTION:

Briefly explain the solution (this will make it easier for the reviewer to confirm that the code does what it should), for example:

• PR changed this because of that.
• We are creating this task to address this problem.

🖼 picture: PRINTS & GIFS:

Include the best screenshots or gifs of the feature if applicable.

(on Macs, ⌘ + ⇧ + 5 is your friend as you can take multiple screenshots/recordings from a fixed window)

💛 MY AMAZING PR CONTAINS:

Does this PR change only one thing (And only what is necessary for it)?

• if not, then why? (e.g., native changes require bureaucratic releases to app stores)
• The Boy Scout Rule is encouraged, but always consider impact and scope when following it.

Awesome tests or e2e (avoid shallow rendering)

• if not, then:
  1. is it a script or configuration file?
  2. something else, and there's a very, very good reason
     • anyway, please explain the situation
