Node Mailer Help

I created a website using React for my mom's business and it has a contact us at the bottom where people can enter their name, email, and message and Node Mailer sends the message to a business email. It worked but it is not working anymore. When I tried doing some research on Google, this is what I found

"Starting January 2025, less secure apps, third-party apps, or devices that have you sign in with only your username and password will no longer be supported for Google Workspace accounts. For exact dates, visit Google Workspace Updates. To continue to use a specific app with your Google Account, you’ll need to use a more secure type of access that doesn’t share password data. Learn how to use Sign in with Google."

How can I fix this issue or is there a better automated email system I can use instead of Node Mailer
