Code closes at first “]”

Hi! (:

First of all: Thank you so much for this simple solution! It is great!!

Now on to the problem..
I think the “[add-to-calendar-button” closes at the first “]” in the code.
I first came across this problem when I included [url] pseudo-tag in the discription parameter. Gave up on figuring it out and then had the idea what the problem is when it happend again when I tried to include a event series.

But I am not sure as I have very basic knowledge. So maybe it’s just my code.

I really hope you can help me. Thanks a lot! (:

Code I used above the vertical line:

[add-to-calendar-button
name="XXX"
description="Alle Infos zu diesem Programmpunkt findest du unter: [url]https://animuc.de/project/XXX[/url]"
location="XXX"

iCalFileName="aniMUC2023-XXX"

startDate="2023-04-28"
endDate="2023-04-28"
startTime="00:00"
endTime="00:00"

options="'Apple','Google','iCal','Outlook.com'"
hideTextLabelButton
hideTextLabelList
buttonStyle="text"
lightMode="light"
styleLight="--btn-text: #4a5da7; --btn-text-hover: #ffffff; --btn-underline: #4a5da7; --btn-text-shadow: none;"
inline
size="1"
timeZone="Europe/Berlin"
]

Code below the vertical line:

[add-to-calendar-button
location="XXX"

iCalFileName="aniMUC2023-XXX"

dates='[
{
"name":"to use the Add to Calendar Button",
"description":"This is the first part to check the Add to Calendar Button script at",
"startDate":"today+3",
"startTime":"10:15",
"endTime":"23:30"
},
{
"name":"to use the Add to Calendar Button",
"description":"This is the third part to check the Add to Calendar Button script at",
"startDate":"today+8",
"startTime":"09:00",
"endTime":"19:00"
},
{
"name":"to use the Add to Calendar Button",
"description":"This is the second part to check the Add to Calendar Button script at",
"startDate":"today+5",
"startTime":"11:30",
"endTime":"20:00"
}
]'

options="'Apple','Google','iCal','Outlook.com'"
hideTextLabelButton
hideTextLabelList
buttonStyle="text"
lightMode="light"
