What's needed to convene a constitutional convention in California?

[alphaboi867]

What needs to happen for a constitutional convention to be held in California? Can a ballot initiative be used to call one or does the legislature need vote on it? I presume replacing the current constitution with an entirely new one would count as a revision, not an amendment.

CALIFORNIA CONSTITUTION
ARTICLE 18 AMENDING AND REVISING THE CONSTITUTION

SEC. 2. The Legislature by rollcall vote entered in the journal,
two-thirds of the membership of each house concurring, may submit at
a general election the question whether to call a convention to
revise the Constitution. If the majority vote yes on that question,
within 6 months the Legislature shall provide for the convention.
Delegates to a constitutional convention shall be voters elected from
districts as nearly equal in population as may be practicable.

I see no provision allowing citizens to bypass the legislature and initiate the convention themselves.
