Creating AddOn minimap button using LibDBIcon

As a developer of PoisonCharges addon (https://www.curseforge.com/wow/addons/poisoncharges) I wanted to update it to the latest WoW Classic version 1.13.2. But I ran into a number of problems trying to remake a minimap button. I tried to use LibDBIcon but can't make it to work because I never worked with libraries when developing addons for WoW.
What I did:
1) copied following libraries to Interface/Addons/PoisonCharges/Libs folder: AceDB-3.0, CallbackHandler-1.0, LibDataBroker-1.1, LibDBIcon-1.0, LibSharedMedia-3.0, LibStub;
2) tried to load them with following XML code (embeds.xml):
Code:
<Ui xmlns="http://www.blizzard.com/wow/ui/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.blizzard.com/wow/ui/
..\FrameXML\UI.xsd">

<[email protected]@-->
<Script file="Libs\LibStub\LibStub.lua"/>
<Include file="Libs\CallbackHandler-1.0\CallbackHandler-1.0.xml"/>
<Include file="Libs\AceDB-3.0\AceDB-3.0.xml"/>
<[email protected]@-->
<Script file="Libs\LibDataBroker-1.1\LibDataBroker-1.1.lua"/>
<[email protected]@-->
<Script file="Libs\LibSharedMedia-3.0\LibSharedMedia-3.0.lua"/>
<Script file="Libs\LibDBIcon-1.0\LibDBIcon-1.0.lua"/>
<[email protected]@-->

</Ui>
3) of course added it to .toc file:
Code:
...

PoisonCharges.lua
PoisonCharges.xml

embeds.xml
4) put following code into OnEvent function (which fires only once when the addon is loaded):
Code:
    local LDB = LibStub("LibDataBroker-1.1", true)
    local LDBIcon = LDB and LibStub("LibDBIcon-1.0", true)
    if LDB then
        local PC_MinimapBtn = LDB:NewDataObject("PoisonCharges", {
            type = "launcher",
			text = "PoisonCharges",
            icon = "Interface\\AddOns\\PoisonCharges\\media\\PoisonCharges_Icon",
            OnClick = function(_, button)
                if button == "LeftButton" then PC_SettingsToggle() end
            end,
            OnTooltipShow = function(tt)
                tt:AddLine("PoisonCharges")
                tt:AddLine("|cffffff00Click|r to open the PoisonCharges settings window.")
            end,
        })
        if LDBIcon then
            LDBIcon:Register("PoisonCharges", PC_MinimapBtn, PC_MinimapPos) -- PC_MinimapPos is a SavedVariable which is set to 90 as default
        end
    end
5) and this is the error I get:
Code:

Thus I'm asking for help: how to make a working movable minimap button for your addon?
