Here's a basic layout of something that prints dispels and steals to your chatframe only.

If you're not familiar with code, you can use https://addon.bool.no to make this an addon.

local f=CreateFrame("frame")
 
function f.COMBAT_LOG_EVENT_UNFILTERED(_,event,_,_,casterName,_,_,_,targetName,_,_,usedSpellID,usedSpellName,_,affectedAuraID,affectedAuraName)
    if event=="SPELL_DISPEL" then
        print(casterName.." dispelled "..targetName.."'s "..affectedAuraName.." using "..usedSpellName)
    elseif event=="SPELL_STOLEN" then
        print(casterName.." stole "..targetName.."'s "..affectedAuraName.." using "..usedSpellName)
    end
end
 
f:SetScript("OnEvent",function(self,event,...)
    if event=="COMBAT_LOG_EVENT_UNFILTERED" then
        self[event](CombatLogGetCurrentEventInfo())
    else
        self[event](...)
    end
end)
 
f:RegisterEvent("COMBAT_LOG_EVENT_UNFILTERED")
