how to write a statuslines for showing cmp sources

[LHAASOIHEP]

cmp type

local function aiStatusCmp(name, icon) 
for _, s in ipairs(require("cmp").core.sources or {}) 
do if s.name == name then 
if not s.source:is_available() then return "🚫" end
 if s.status == s.SourceStatus.FETCHING then return "⌛️" end 
 return icon end end end

is there some simular function of sources.is_avail() source.status and so on
