1 year ago ftr, among others, simplex also allows using a qr code, eg. https://simplex.chat/invitation/#/?v=1-4&smp=smp%3A%2F%2FSkIkI6EPd2D63F4xFKfHk7I1UGZVNn6k1QWZ5rcyr6w%3D%40smp9.simplex.im%2FxFV_q4trjZPstMNdhM3FroxT8ecGU2pY%23%2F%3Fv%3D1-2%26dh%3DMCowBQYDK2VuAyEA4R_iYVRMjkHxW1KOHrkqFnepyzjAYiZRfrT9IJS-jhc%253D%26srv%3Djssqzccmrcws6bhmn77vgmhfjmhwlyr3u7puw4erkyoosywgl67slqqd.onion&e2e=v%3D1-2%26x3dh%3DMEIwBQYDK2VvAzkA9-6mVuBbmV3ilnmpjfwP8Quxwd9KgFlFdDquAog6KMpfM7qo-SizEQImVcLP1nwbW8_aTyOR14g%3D%2CMEIwBQYDK2VvAzkA7QH4Yn5bTZXgn5_tuAxD5r0GInPy0Qudz16k_Jbpo7ZxNXk9VNOd3swRCjzxaKNmJtU76Ej7VVo%3D (via https://support.delta.chat/t/making-joining-groups-easier-qr-scan-progress/2831 )
i would not take the simplex as a good example, through, it seems a bit wordy and the url code is also a bit long (maybe there are shorter forms available, idk)
that would make the page even more useful.
you could eg. get the page on one device and join there with a "tap" - or join from another device with a "scan"
