For additional reference, you can check out this forum post:
URL Parameter in Public URL β Retool Community
Please note that the forum example uses an older version of Retool, so the "Pages" and "Inspector" sections may look slightly different. Donβt let that cause any confusion.
Please let me know if you need any assistance with configuration.
