Uruguay is currently using a pre-Rainbow build, so this should work.

The alternative, under Rainbow, is to do what Chat does: create a
journal entry with a mime-type of text/uri-list, and call
show_object_in_journal to switch to the journal view of that object so
it can be launched with a click:

Hopefully Rainbow will grow a mechanism for activities to request it
to launch other activities given certain restrictions.
