Once you've completed all of the prerequisites, head to The Rain's End via the Teleport Waypoint below Apam Woods, circled in the image above. If you don't see this Teleport Waypoint in your World Map, you might have forgotten to unlock it while doing the Varuna Gatha questline, so you can head to the Varunastra in the middle of Apam Woods and jump down the entrance to find the hidden Waypoint. Once you're underground, head toward the Domain through the path the arrow points to above.

You'll find a barrier blocking the Domain, and must solve a puzzle to disperse it. Apply Dendro onto the Elemental Monument to prompt green traces to appear. Follow the green traces to find a Sprouting Branch.

Equip the Vintage Lyre and follow the prompts to play the Rhythm of the Sprout (do > so > so > la > ti on the third row) to revive the Sprouting Branch. Interact with it to summon Healthy Dendrogranum, then follow the green traces back to the Elemental Monument.

A floating projectile will appear above the Elemental Monument. While the Healthy Dendrogranum is still active, shoot the floating projectile with an archer to disperse the barrier, allowing you to enter the cave housing The Coordinates of Sun and Rain Domain. Don't forget to interact with it at least once to unlock it.
