Change autoplay Timeout

Hello,

I try to make a slider using B Carousel.
The images in this slider have some text. I hope to stay on each images for a long time when it is autoplay, so that the user can read the text.
I saw that there is a “speed” field that can be adjusted in the default setting options, but after actually changing it, I found that it was only the speed of image switching, not the length of time the image stayed.
Can I use additional settings to meet my needs?

thanks
