Currently, it displays an alert when clicked, but it's designed to be easily modified for more advanced functionality.\n\n## Modifying the Help Widget\n\nThe help widget is implemented in a modular way through the `getHelpWidgetHtml()` function. To change its appearance or functionality:\n\n1. Locate the `getHelpWidgetHtml()` function in the code\n2. Modify the HTML, CSS, or JavaScript as needed\n3. The widget's functionality is contained within the embedded script tag\n\n## Implementation Details\n\n- The proxy uses standard fetch API to forward requests\n- URL transformation handles both absolute and relative URLs\n- The widget is injected before the closing `` tag when possible",[138],"pulls","branches","forks","envVars",{"_151":61,"_153":61},"connections",{"_151":61,"_152":61},"count","unfilledCount","emptyCount",{"_43":137,"_32":138,"_30":139,"_130":-5,"_41":42,"_40":140,"_131":57,"_38":160,"_13":133,"_33":20,"_35":142,"_24":25,"_134":-5,"_157":161,"_27":162},{"_43":129,"_32":28,"_30":31,"_130":-5,"_41":42,"_40":14,"_131":25,"_38":156,"_13":133,"_33":34,"_35":37,"_24":25,"_134":135,"_157":158,"_27":159},["D",1749426146039],"children",[],[28],["D",1749424985197],[],[138],["D",1749424906988],{"_97":96,"_104":100},{"_97":96,"_98":-5,"_99":100,"_18":54,"_101":102,"_103":25},{"_13":84,"_32":85,"_43":42,"_86":44,"_87":-5,"_88":-5,"_89":90,"_91":92,"_93":63,"_94":45,"_95":96},"ctx",{"_77":-5,"_124":200,"_201":202,"_203":204,"_205":25,"_206":25,"_207":25,"_208":57,"_209":-5,"_210":-7,"_211":-7,"_212":61,"_213":25,"_214":25,"_215":-5,"_216":25,"_217":25,"_218":25,"_219":-5},"ENV",{"_171":172,"_173":174,"_175":85,"_176":177,"_178":179,"_180":181,"_182":183,"_184":185,"_186":187,"_188":189,"_190":191,"_192":193,"_194":195,"_196":197,"_198":199},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","c73f21da490985bff19c279eb0e09db24d688e4f","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
