Answer:
The method what I used thast the person what you would like to add make them make a question then find the question by searching it up or looking in the 'answer questions' category. After that answer the question or just write anny thing in the question. Let your friend comment or interact with the answer them click on there profile and add. If you what them to add you back they will have to go on there profile and then go to there followers and click add back.
