How do I personalize the theta theme buttons?

[Lucashdml]

this are my configs
{
"goolord/alpha-nvim",
lazy = false,
dependencies = {
"nvim-tree/nvim-web-devicons",
"nvim-lua/plenary.nvim",
},
config = function()
local alpha = require ("alpha")
local config = require("alpha.themes.theta").config
-- there's no name, access via index
config.layout[2].val = {
[[ ]],
[[ ]],
[[ ]],
[[ ]],
[[  ]],
[[ ████ ██████ █████ ██ ]],

Hey did you find out anything? I just came across this same issue, seems like you might need to copy paste the whole theta theme and modify the buttons but I wonder if there's an easier way
