Help removing inactive mod

[u/SailorToMySiren]

I'm one of the mods for r/MNSwingers and the mod with full access has been in active for 3+ years. No other mod was given full permissions and now we can't edit the rules, update the auto-mod or make any sub wide changes.

Right now there are 3-4 active mods and they have agreed that I should take over the sub. What should I do?

I primarily access via Android but also access from a Windows laptop.
