Can someone submit a certificate of residence application on behalf of another person in Thailand?

In Thailand, it is generally required for the applicant to submit the certificate of residence application in person. However, there are exceptions where a Thai Power of Attorney may allow someone to submit the application on behalf of the applicant. Some users noted that certain agents or representatives, like those from a motorbike dealer, have been able to handle such submissions, implying that delegation is possible under specific conditions.
