Using Web Search Capabilities for Open-ai

On ChatGPT.com, I have a custom GPT that visits a lead’s website, tries to find the booking link, and follows it to determine which booking system the lead is using. When I initially built the GPT, I received random answers until I enabled Web Search capabilities. Now, I’m trying to automate this process using Make, but I’m getting random answers again, which reminds me of the Web Search issue. Is there any way to enable it?
