I tried restarting studio multiple times, tried to watch a few videos to make sure I wasn’t doing anything wrong and I also tried to re-check the proximity prompt feature in the beta features list. None of it worked.
By default Studio only shows recommended objects; looks like ProximityPrompt wasn’t added as a suggestion for inserting objects into BaseParts. Click on the arrow at the top right then tick Show only recommended objects
Thank you so much! It worked, also sorry for being a bit vague in the post, I’m aware that this isn’t the best post as it’s not a serious issue, sorry about that!
