Hi there, I am trying to run a set of 3 dependent flows meant to be run sequentially (A->B->C). Is there a way I can have both a schedule for this flow (as stated here) and also have a manual trigger to the said parent flow ? What options do I have to manually trigger the 'parent-flow' apart from prefectUI and GraphQL ?

Those are the only options I think. Are you looking for something else? You can manually run a flow even if there is a schedule.
