Acabei de escrever algumas linhas de código e fiquei preso tentando adicionar um botão de detalhe ao meu ponto de anotação, não sei como. Alguém sabe como fazer isso? A imagem abaixo mostra o que eu quero alcançar. Obrigado!

Estou tentando colocar o grande eu no círculo na minha anotação.

No momento, só tenho uma anotação com um título e uma legenda, que se parece com abaixo.

Além disso, se você sabe, quando um usuário clica no i no círculo, como os trago para uma nova segue?

Obrigado pela ajuda.
