Does Disciple of Life work with spells cast from a Staff of Healing? [duplicate]

Question

If I have a Cleric who is Life domain and a Staff of Healing does Disciple of Life work with the spells cast from the Staff?

Staff of Healing: While holding it, you can use an action to expend 1 or more of its charges to cast one of the following spells from it, using your spell save DC and spellcasting ability modifier: [spells follow]

Disciple of Life: Also starting at 1st level, your healing spells are more effective. Whenever you use a spell of 1st level or higher to restore hit points to a creature, the creature regains additional hit points equal to 2 + the spell’s level

Answer 1

Yes, Disciple of Life applies to spells from the staff.

The staff ultimately allows you to cast the spells from it ("you can use an action to [...] cast one of the following spells from it"), and Disciple of Life applies to all spells you cast; it makes no restrictions along the lines of 'Whenever you use a cleric spell of 1st level or higher' that would prevent it from applying to the staff's spells.
