You were shown. There is no reason to have it written since any such right would mean there was no constitution.
Our Founders were not such idiots that they would put a self-destruct mechanism within the document. It was meant to last forever like the perpetual Union.
States had ONE chance to legally leave and that only covered the original thirteen. ALL the other states were CREATIONS of Congress entirely. All states had almost every necessary aspect of sovereignty removed by Article I, Section 10. There was not even a right to call conventions to proclaim secession.
And even if there were such a right lurking in the penumbras there certainly was no right to attack federal property and personnel.
If it isn't stated in the Constitution, then it doesn't count.
There is NO perpetual Union clause. And Texas had the right of secession from the time it joined the Union (by treaty).
If indeed the right of secession exists, then from the time South Carolina seceded, Ft. Sumter was no longer Federal property, and if so, then keeping a garrison in it was an illegal act, which would justify an attack.
that's why you are a laughingstock to all here.

SECESSION is just ONE of those "reserved" powers.
NO state would have FREELY joined a union from which they couldn't just as FREELY depart. even YOU should be smarter than to believe the stupid garbage that you routinely post. otoh, perhaps you think or HOPE that your readers are dumbER than you seem to be.
laughing AT you & your IGNORANT bilge.
