I cannot apply for access verification of FB app. The reason is that I am not certified by tech-providers as shown in the attached image.

How do I become a tech-provider? I can't find the application form.

I didn't know how to specifically become a tech-provider even after reading the support content below.

Can someone tell me how to become a tech-provider? Please tell me how to apply to FB.
