List a member's connected accounts

curl https://api.subscriby.net/v1/projects/$PROJECT_ID/members/$MEMBER_ID/identities \  -H "Authorization: Bearer $SUBSCRIBY_TOKEN"

The member's connected accounts, preferred first. Never paginated. A member can connect one account per platform the project is on, from the portal's Account & Recovery screen or by talking to the project's bot; the member read embeds the same rows as identities. Connecting has no endpoint: it is a two-sided proof the member completes on the connector.

• id is the link, which is what the disconnect endpoint takes; external_id is the platform's own id for the account.
• source says how the link was proven: handshake (connected from the portal and confirmed by the bot, or a portal sign-in), adopted (taken over from another of the creator's projects), portal, bot (the bot met the account first) or backfill (migrated from before connectors).
• preferred marks the account the project reaches first; a member's first account is, and the member can move it on the portal.
• notify marks a further account the member switched the project's notices on for, from the portal. The preferred account always hears them, so it reads false there too; a grant notice stays on the connector of the grant and a support reply on the connector the member wrote from, whatever the switches say.
