How to add an icon for a service?

I'm developing an integration with Todoist.

Currently, no icon is shown on the team member page and a generic "link" icon is shown on the timer widget of the Chrome extension.

Is there a way to specify the icon for the service where the permalink is located? If it's done on your end and you are willing to add an icon for this, I'm using the `applicationName` "Todoist".
